00:00:00:01 - 00:00:02:02 Welcome to Live Well with UCI Health. 00:00:02:02 - 00:00:04:10 I am Ryan Manno from KOST 103.5 00:00:04:10 - 00:00:05:08 and iHeartRadio. 00:00:05:08 - 00:00:06:16 I am thrilled to be joined today 00:00:06:16 - 00:00:08:03 by Doctor Stefan Ciurea, 00:00:08:03 - 00:00:10:13 director of the Hematopoietic Stem Cell 00:00:10:13 - 00:00:12:19 Transplant and Cellular Therapy Program. 00:00:12:19 - 00:00:13:15 Correct. 00:00:13:15 - 00:00:15:01 It's the first adult program 00:00:15:01 - 00:00:16:03 in Orange County 00:00:16:03 - 00:00:16:22 to use stem cells, 00:00:16:22 - 00:00:18:10 which are found in blood and bone marrow, 00:00:18:10 - 00:00:20:04 to treat blood and lymph cancers, 00:00:20:04 - 00:00:22:08 genetic diseases and immune disorders. 00:00:22:08 - 00:00:23:12 That sounds like important stuff. 00:00:23:12 - 00:00:24:05 It provides life 00:00:24:05 - 00:00:25:23 saving cell therapy infusions 00:00:25:23 - 00:00:27:11 to more than 120 patients per year. 00:00:27:11 - 00:00:28:01 Doctor Ciurea, 00:00:28:01 - 00:00:29:11 thank you so much for your time today. 00:00:29:11 - 00:00:30:11 Thank you for having me. 00:00:30:11 - 00:00:31:23 Let's just get into it because I, 00:00:31:23 - 00:00:32:04 you know, 00:00:32:04 - 00:00:32:21 I think I'm going to speak 00:00:32:21 - 00:00:33:17 for a lot of people here. 00:00:33:17 - 00:00:36:17 You hear stem cell, stem cell, stem cell 00:00:36:18 - 00:00:37:03 a lot. 00:00:37:03 - 00:00:37:23 But I don't know that 00:00:37:23 - 00:00:38:23 many people know what it is. 00:00:38:23 - 00:00:39:17 So let's start there. 00:00:39:17 - 00:00:40:21 What are stem cells? 00:00:40:21 - 00:00:45:15 Stem cells are a small number of immature 00:00:47:08 - 00:00:49:18 cells in different organs in 00:00:49:18 - 00:00:53:13 the body that have renewal potential. 00:00:54:15 - 00:00:56:11 They have specific characteristics. 00:00:56:11 - 00:00:58:05 They are quiescent, we call them. 00:00:58:05 - 00:01:00:18 And with self-renewal potential 00:01:00:18 - 00:01:03:03 different than differentiated cells, 00:01:03:03 - 00:01:04:07 which are cells 00:01:04:07 - 00:01:06:00 that have gone through maturation 00:01:06:00 - 00:01:07:03 and they are going to die. 00:01:07:03 - 00:01:09:12 These cells are not dying cells. 00:01:09:12 - 00:01:10:14 They are quiescent 00:01:10:14 - 00:01:14:19 cells in a in a state that allows them 00:01:14:19 - 00:01:16:12 to generate 00:01:16:12 - 00:01:17:17 differentiated cells 00:01:17:17 - 00:01:19:15 in different organs and tissues. 00:01:19:15 - 00:01:21:01 Okay. Quiescent. 00:01:21:01 - 00:01:22:08 Is that the word you use? Yes. 00:01:22:08 - 00:01:23:11 What does that mean? 00:01:23:11 - 00:01:26:19 Means that they are not rapidly dividing. 00:01:26:20 - 00:01:30:05 They are in a dormant state if you want. 00:01:30:06 - 00:01:32:20 Okay. So where do we find these cells. 00:01:32:20 - 00:01:33:16 These stem cells. 00:01:33:16 - 00:01:36:05 These are found in different tissues 00:01:36:05 - 00:01:40:00 and organs as far as we are concerned 00:01:40:10 - 00:01:43:16 in the bone marrow of a recipient. 00:01:43:17 - 00:01:44:06 Okay. 00:01:44:06 - 00:01:46:22 How do you know where 00:01:46:22 - 00:01:48:04 which ones are the stem cells 00:01:48:04 - 00:01:49:08 and which ones aren't. 00:01:49:08 - 00:01:50:18 So we 00:01:50:18 - 00:01:51:15 we are able 00:01:51:15 - 00:01:53:08 to identify hematopoietic. 00:01:53:08 - 00:01:54:04 So there are different 00:01:54:04 - 00:01:55:02 types of stem cells 00:01:55:02 - 00:01:56:17 in different organs and tissues 00:01:56:17 - 00:01:57:17 as I mentioned. 00:01:57:17 - 00:01:59:12 For hematopoietic stem 00:01:59:12 - 00:02:02:06 cells we are able to identify them 00:02:02:06 - 00:02:06:00 by a certain surface markers. Okay. 00:02:06:00 - 00:02:08:02 So do you know going in 00:02:08:02 - 00:02:09:04 where the stem cells 00:02:09:04 - 00:02:10:22 are going to be harvested 00:02:10:22 - 00:02:12:03 from for lack of a better word? 00:02:12:03 - 00:02:13:02 Or is it kind of like, 00:02:13:02 - 00:02:13:09 I don't know 00:02:13:09 - 00:02:15:20 if you're trying to catch crab 00:02:15:20 - 00:02:17:11 and you throw a net in 00:02:17:11 - 00:02:19:02 and you just pull out what you get 00:02:19:02 - 00:02:20:08 and then find them. 00:02:20:08 - 00:02:21:14 Cells are in the bone 00:02:21:14 - 00:02:24:19 marrow, hematopoietic stem cells. 00:02:25:12 - 00:02:27:02 These are different, for example, 00:02:27:02 - 00:02:28:07 than embryonic stem cells. 00:02:28:07 - 00:02:29:01 Embryonic stem 00:02:29:01 - 00:02:30:16 cells are the most immature 00:02:30:16 - 00:02:31:19 and the cells 00:02:31:19 - 00:02:33:05 that have the potential 00:02:33:05 - 00:02:34:05 to differentiate 00:02:34:05 - 00:02:36:20 in all cells 00:02:36:20 - 00:02:39:01 from different organs in the body. 00:02:39:01 - 00:02:41:19 Our stem cells are a little bit 00:02:41:19 - 00:02:46:14 more programed to develop in blood cells, 00:02:46:19 - 00:02:49:14 including red blood cells, platelets, 00:02:49:14 - 00:02:49:23 white 00:02:49:23 - 00:02:51:19 cells, and cells 00:02:51:19 - 00:02:54:15 that are part of the immune system. 00:02:54:15 - 00:02:55:03 Okay. 00:02:55:03 - 00:02:57:22 So we we they are in the bone marrow. 00:02:57:22 - 00:02:59:12 And in order to collect them 00:02:59:12 - 00:03:02:17 and infuse them for this procedure, 00:03:02:21 - 00:03:04:22 we either collect them from them 00:03:04:22 - 00:03:06:02 directly from the bone marrow 00:03:06:02 - 00:03:09:04 in the operating room or from the... one’s 00:03:09:04 - 00:03:12:13 blood after stem cell mobilization. 00:03:12:13 - 00:03:15:05 So what is stem cell transplantation? 00:03:15:05 - 00:03:17:16 Stem cell transplantation is a procedure, 00:03:17:16 - 00:03:19:06 a quite complex procedure, 00:03:19:06 - 00:03:21:00 in which we give a patient 00:03:21:00 - 00:03:23:07 high dose of chemotherapy 00:03:23:07 - 00:03:26:23 to eliminate some residual disease 00:03:27:04 - 00:03:30:04 or prevent relapse of a disease, 00:03:30:07 - 00:03:31:14 followed by infusion 00:03:31:14 - 00:03:32:08 of cells 00:03:32:08 - 00:03:33:06 of these stem cells 00:03:33:06 - 00:03:34:21 to reconstitute the bone 00:03:34:21 - 00:03:36:20 marrow of the recipient. 00:03:36:20 - 00:03:38:06 These stem cells 00:03:38:06 - 00:03:41:06 can be collected from the patient 00:03:41:15 - 00:03:43:03 when patient is in remission 00:03:43:03 - 00:03:44:17 for certain diseases, 00:03:44:17 - 00:03:46:13 or from a donor, 00:03:46:13 - 00:03:49:01 in the form of an allogeneic stem 00:03:49:01 - 00:03:49:20 cell transplant, 00:03:49:20 - 00:03:50:18 which means stem 00:03:50:18 - 00:03:53:19 cell transplant with a donor that 00:03:54:03 - 00:03:57:04 donates normal stem cells 00:03:58:03 - 00:03:58:15 for a 00:03:58:15 - 00:04:02:12 disease that that requires this therapy. 00:04:02:13 - 00:04:03:05 How do you know 00:04:03:05 - 00:04:05:01 who's a good donor for somebody? 00:04:05:01 - 00:04:06:07 Like if I needed stem cells, 00:04:06:07 - 00:04:06:22 if you're like, okay, 00:04:06:22 - 00:04:08:22 I think you need this, how where would 00:04:08:22 - 00:04:10:07 how would we find a donor? 00:04:10:07 - 00:04:14:02 So so it depends a lot on the disease 00:04:14:05 - 00:04:14:21 the patient has. 00:04:14:21 - 00:04:16:00 So would it be like my family? 00:04:16:00 - 00:04:17:07 Would you start with my family 00:04:17:07 - 00:04:19:10 because we know they were closer match. 00:04:19:10 - 00:04:22:01 There are two main types of transplants 00:04:22:01 - 00:04:22:19 okay. 00:04:22:19 - 00:04:23:14 An autologous 00:04:23:14 - 00:04:25:01 transplant is a transplant with 00:04:25:01 - 00:04:27:16 with the patient's own stem cells. 00:04:27:16 - 00:04:28:14 An allogeneic 00:04:28:14 - 00:04:29:07 transplant 00:04:29:07 - 00:04:31:02 is a transplant 00:04:31:02 - 00:04:33:05 with stem cells from a donor. 00:04:33:05 - 00:04:35:18 And these are 00:04:35:18 - 00:04:37:11 we use these procedures 00:04:37:11 - 00:04:39:05 based on one's disease. 00:04:39:05 - 00:04:39:17 For example 00:04:39:17 - 00:04:42:17 for patients with lymphoma or myeloma 00:04:43:05 - 00:04:45:15 we do mostly autologous transplants. 00:04:45:15 - 00:04:46:23 Transplants with own stem cells. 00:04:46:23 - 00:04:48:12 So patient gets chemotherapy 00:04:48:12 - 00:04:49:19 goes into remission. 00:04:49:19 - 00:04:53:03 And we do to consolidate remission 00:04:53:03 - 00:04:55:14 and/or prevent disease coming back. 00:04:55:14 - 00:04:58:22 We collect their own stem cells and 00:04:58:22 - 00:05:01:13 and do the transplant 00:05:01:13 - 00:05:02:15 with their own stem cells. 00:05:02:15 - 00:05:04:01 We give them high dose chemotherapy 00:05:04:01 - 00:05:06:01 and infuse these cells back to them. 00:05:06:01 - 00:05:09:07 For allogeneic transplants 00:05:09:22 - 00:05:12:20 we use a donor to donate stem cells. 00:05:12:20 - 00:05:14:03 And we admit the patient 00:05:14:03 - 00:05:15:14 give the patient recipient 00:05:15:14 - 00:05:16:21 high doses of chemotherapy 00:05:16:21 - 00:05:18:11 and infuse the cells from the donor. 00:05:18:11 - 00:05:20:08 And this is done for different diseases 00:05:20:08 - 00:05:21:14 like leukemias 00:05:21:14 - 00:05:24:04 or myelodysplastic syndromes. 00:05:24:04 - 00:05:27:04 How do they work, then, to save lives? 00:05:27:05 - 00:05:28:05 A life is saved 00:05:28:05 - 00:05:30:02 by preventing a relapse 00:05:30:02 - 00:05:32:00 or preventing progression of disease. 00:05:32:00 - 00:05:32:17 In essence. 00:05:32:17 - 00:05:33:02 Okay, 00:05:33:02 - 00:05:36:01 so we do this procedure to prevent 00:05:36:01 - 00:05:37:10 a relapse. 00:05:37:10 - 00:05:38:22 Relapse will kill the patient. 00:05:38:22 - 00:05:40:14 So tell me kind of like in basic terms. 00:05:40:14 - 00:05:41:11 So you know 00:05:41:11 - 00:05:43:07 just so everyone can kind of follow here 00:05:43:07 - 00:05:46:04 you you put stem cells in somebody to 00:05:46:04 - 00:05:46:17 you know, 00:05:46:17 - 00:05:47:06 you've given them 00:05:47:06 - 00:05:48:08 the high dose chemotherapy. 00:05:48:08 - 00:05:49:18 You've got the stem cells in. 00:05:49:18 - 00:05:53:11 What is occurring inside of their body, 00:05:54:13 - 00:05:54:22 you know? 00:05:54:22 - 00:05:55:20 To... That’s a good question. 00:05:55:20 - 00:05:58:16 To to make these things do their job? 00:05:58:16 - 00:05:59:00 Right. 00:05:59:00 - 00:06:02:20 So so we rely for certain diseases 00:06:02:20 - 00:06:04:13 like lymphomas and myeloma. 00:06:04:13 - 00:06:05:01 As I mentioned, 00:06:05:01 - 00:06:08:17 we rely on the chemotherapy to 00:06:08:18 - 00:06:11:01 to eliminate any residual disease 00:06:11:01 - 00:06:12:18 and prevent relapse. Got it. 00:06:12:18 - 00:06:14:03 And the stem cells 00:06:14:03 - 00:06:15:08 we give to reconstitute 00:06:15:08 - 00:06:16:14 the one’s bone marrow 00:06:16:14 - 00:06:20:09 and immune system and blood cells, we we 00:06:20:10 - 00:06:23:12 we give them to reconstitute 00:06:23:13 - 00:06:25:19 the the otherwise the bone marrow. 00:06:25:19 - 00:06:27:06 If we don't infuse the stem 00:06:27:06 - 00:06:28:22 cells, patient will remain... 00:06:28:22 - 00:06:29:11 Maybe 00:06:29:11 - 00:06:32:11 disease is not going to come back but 00:06:32:11 - 00:06:33:15 will not have a bone 00:06:33:15 - 00:06:35:22 marrow, will not have 00:06:35:22 - 00:06:38:07 blood cells or immune system. 00:06:38:07 - 00:06:40:07 And this is not compatible with life. 00:06:40:07 - 00:06:43:16 So so it's it's also called high dose 00:06:43:16 - 00:06:46:16 chemotherapy and stem cell rescue. 00:06:46:16 - 00:06:47:08 In other words, 00:06:47:08 - 00:06:49:23 we rescue the bone marrow for a patient 00:06:49:23 - 00:06:51:02 after we gave high dose 00:06:51:02 - 00:06:52:08 chemotherapy with the goal 00:06:52:08 - 00:06:53:16 to eliminate the disease. 00:06:53:16 - 00:06:54:07 When is it 00:06:54:07 - 00:06:55:21 time to do stem cells 00:06:55:21 - 00:06:57:10 like a transplantation? Right. 00:06:57:10 - 00:06:57:19 Right. 00:06:57:19 - 00:06:58:14 It again 00:06:58:14 - 00:07:02:00 depends on on disease and disease type. 00:07:03:08 - 00:07:05:19 And the general rule is 00:07:05:19 - 00:07:07:19 we want to take a patient to transplant 00:07:07:19 - 00:07:08:20 when is in remission 00:07:08:20 - 00:07:10:03 for an autologous transplant 00:07:10:03 - 00:07:12:03 and also for an allogeneic transplant. 00:07:12:03 - 00:07:13:00 For example, a patient 00:07:13:00 - 00:07:14:08 with acute myeloid leukemia. 00:07:14:08 - 00:07:15:13 They usually go through induction 00:07:15:13 - 00:07:16:16 chemotherapy 00:07:16:16 - 00:07:18:22 and consolidation chemotherapy. 00:07:18:22 - 00:07:20:08 They are in remission. 00:07:20:08 - 00:07:23:01 And while 00:07:23:01 - 00:07:23:20 they are in remission, 00:07:23:20 - 00:07:24:22 we start to prepare 00:07:24:22 - 00:07:27:20 for the actual transplant, 00:07:27:20 - 00:07:29:03 contacting the donor 00:07:29:03 - 00:07:31:14 and setting up the collection 00:07:31:14 - 00:07:33:23 and the actual 00:07:33:23 - 00:07:35:12 chemotherapy and infusion 00:07:35:12 - 00:07:36:23 of cells in the hospital. Right. 00:07:36:23 - 00:07:37:10 So are you 00:07:37:10 - 00:07:38:20 the one that makes that decision 00:07:38:20 - 00:07:40:00 and says, look, yes. 00:07:40:00 - 00:07:41:00 Yeah, yeah. 00:07:41:00 - 00:07:43:09 So cell transplant doctor. Right. 00:07:43:09 - 00:07:45:01 Makes the decision 00:07:45:01 - 00:07:46:03 which disease, 00:07:46:03 - 00:07:49:01 what type of transplant is needed 00:07:49:01 - 00:07:51:22 for patient’s condition. Yeah. 00:07:51:22 - 00:07:54:03 And what's the most common condition. 00:07:54:03 - 00:07:58:04 Disease that you that you would recommend 00:07:58:11 - 00:07:59:02 stem cells. 00:07:59:02 - 00:08:02:02 So autologous transplants are mostly done for 00:08:02:23 - 00:08:05:23 my... multiple myeloma and lymphomas. 00:08:06:05 - 00:08:07:09 Allogeneic transplants 00:08:07:09 - 00:08:08:18 are mostly done for acute 00:08:08:18 - 00:08:09:18 myeloid leukemia, 00:08:09:18 - 00:08:11:18 acute lymphoblastic leukemia 00:08:11:18 - 00:08:14:05 and myelodysplastic 00:08:14:05 - 00:08:16:06 myeloproliferative diseases. 00:08:16:06 - 00:08:16:18 Yeah. 00:08:16:18 - 00:08:19:08 Which one of those would you say 00:08:19:08 - 00:08:20:01 have you found... 00:08:20:01 - 00:08:21:01 And maybe there's no answer to 00:08:21:01 - 00:08:23:21 this has the best success rate 00:08:23:21 - 00:08:26:03 like which one of those diseases 00:08:26:03 - 00:08:27:16 is best treated by this? 00:08:27:16 - 00:08:29:01 It's difficult to answer the question 00:08:29:01 - 00:08:29:10 because 00:08:29:10 - 00:08:31:03 because it really depends on on 00:08:31:03 - 00:08:33:20 on the on the disease. 00:08:33:20 - 00:08:34:05 Okay. 00:08:34:05 - 00:08:37:05 So just I can give you some examples. 00:08:37:09 - 00:08:38:18 But it also for, for 00:08:38:18 - 00:08:40:01 allogeneic transplants 00:08:40:01 - 00:08:41:11 for example depends a lot. 00:08:41:11 - 00:08:45:19 Success depends a lot on one's risk. 00:08:45:19 - 00:08:46:17 Disease risk. 00:08:46:17 - 00:08:49:06 So there are different flavors I say 00:08:49:06 - 00:08:50:23 in general of 00:08:51:22 - 00:08:52:12 for example 00:08:52:12 - 00:08:55:12 acute myeloid leukemia has different. 00:08:56:10 - 00:08:59:10 It's it's a mixture of different diseases 00:08:59:14 - 00:09:00:22 with different risks. 00:09:00:22 - 00:09:05:11 So outcomes depend on disease 00:09:05:11 - 00:09:08:21 risks also disease risk in general also. 00:09:09:06 - 00:09:10:17 So we tend to do 00:09:10:17 - 00:09:12:01 the same type of transplant. 00:09:12:01 - 00:09:13:09 But outcomes may be different 00:09:13:09 - 00:09:15:03 because somebody has higher 00:09:15:03 - 00:09:16:09 risk disease than... 00:09:16:09 - 00:09:17:18 Yes, that makes sense to me 00:09:17:18 - 00:09:18:14 I get that now. 00:09:18:14 - 00:09:21:06 So let's talk about like 00:09:21:06 - 00:09:22:19 the procedure itself. 00:09:22:19 - 00:09:24:08 Are there risks involved. 00:09:24:08 - 00:09:25:12 There are actually 00:09:25:12 - 00:09:29:01 and this is the main issue with this 00:09:29:18 - 00:09:31:17 with stem cell transplantation. 00:09:31:17 - 00:09:33:10 And the risks are derived 00:09:33:10 - 00:09:34:22 from the fact that we're dropping 00:09:34:22 - 00:09:35:15 blood counts 00:09:35:15 - 00:09:36:18 and patients are exposed to 00:09:36:18 - 00:09:38:12 infectious complications. 00:09:38:12 - 00:09:39:12 And in addition, 00:09:39:12 - 00:09:41:11 with changing the immune system 00:09:41:11 - 00:09:43:19 with that of the donor. So in the. 00:09:43:19 - 00:09:46:16 So the allogeneic transplant recipient 00:09:46:16 - 00:09:48:01 gets a new immune system, 00:09:48:01 - 00:09:49:03 which is immature. 00:09:49:03 - 00:09:51:07 It's like a newborn immune system. 00:09:51:07 - 00:09:52:10 Whoa. That's cool. 00:09:52:10 - 00:09:54:17 And then we actually vaccinate 00:09:54:17 - 00:09:55:19 these patients 00:09:55:19 - 00:09:59:19 for a period of two years with all, all 00:10:01:01 - 00:10:01:21 baby shots 00:10:01:21 - 00:10:04:14 that... No way... one gets in. 00:10:04:14 - 00:10:05:16 Yeah. 00:10:05:16 - 00:10:06:13 So we 00:10:06:13 - 00:10:08:00 they get a lot of shots 00:10:08:00 - 00:10:09:04 over a period of two years. 00:10:09:04 - 00:10:10:08 Because it's like starting over. 00:10:10:08 - 00:10:12:14 Starting over for the 00:10:12:14 - 00:10:13:15 with a new immune system. 00:10:13:15 - 00:10:14:21 And because they have 00:10:14:21 - 00:10:17:18 an immature immune system, 00:10:17:18 - 00:10:20:16 they are at risk to develop different 00:10:20:16 - 00:10:21:18 types of infections, 00:10:21:18 - 00:10:22:22 which we monitor 00:10:22:22 - 00:10:25:13 very closely, prevent and treat 00:10:25:13 - 00:10:26:10 if they occur. 00:10:26:10 - 00:10:26:22 Yeah. 00:10:26:22 - 00:10:30:09 Is the process itself painful? 00:10:30:10 - 00:10:32:03 It's not painful really. 00:10:32:03 - 00:10:33:03 I mean, there's 00:10:33:03 - 00:10:34:07 there's some discomfort 00:10:34:07 - 00:10:37:07 related to using central lines or 00:10:37:13 - 00:10:39:09 but it's not a painful, 00:10:39:09 - 00:10:40:12 necessarily procedure. 00:10:40:12 - 00:10:42:05 It doesn't involve surgery. 00:10:42:05 - 00:10:44:05 It's not painful procedure. 00:10:44:05 - 00:10:45:02 How do you do it? 00:10:45:02 - 00:10:45:23 I mean, how do you like. 00:10:45:23 - 00:10:47:18 Because I would think that if you're 00:10:47:18 - 00:10:49:20 taking stem cells out of my bone marrow, 00:10:49:20 - 00:10:51:11 I can't imagine that that would be fun. 00:10:51:11 - 00:10:52:18 Or putting them in there. 00:10:52:18 - 00:10:53:12 Well, yes. 00:10:53:12 - 00:10:55:23 So if we take the stem cells 00:10:55:23 - 00:10:58:02 directly from the bone marrow 00:10:58:02 - 00:11:00:00 through a bone marrow harvest procedure, 00:11:00:00 - 00:11:01:16 procedure in the operating room, 00:11:01:16 - 00:11:02:06 we take 00:11:02:06 - 00:11:04:19 the patient gets a general anesthesia. 00:11:04:19 - 00:11:06:13 But it's really 00:11:06:13 - 00:11:08:10 rare nowadays to use stem cells 00:11:08:10 - 00:11:10:01 directly from the bone marrow. 00:11:10:01 - 00:11:11:06 We still do it 00:11:11:06 - 00:11:13:05 for very specific indications. 00:11:13:05 - 00:11:16:09 So that's probably the only situation 00:11:16:09 - 00:11:17:16 in which if we collect 00:11:17:16 - 00:11:18:22 we have to collect the cells. 00:11:18:22 - 00:11:20:20 We want to collect the cells 00:11:20:20 - 00:11:22:19 directly from the bone marrow. 00:11:22:19 - 00:11:23:11 Patient goes 00:11:23:11 - 00:11:24:17 to the operating room, 00:11:24:17 - 00:11:26:17 goes undergoes general anesthesia. 00:11:26:17 - 00:11:30:00 And with two needles we go into 00:11:30:00 - 00:11:32:12 pelvic bones... Pelvic bones, got it. 00:11:32:12 - 00:11:33:10 right in the back. 00:11:33:10 - 00:11:35:01 And why there? 00:11:35:01 - 00:11:38:19 Because there's the these are the points 00:11:39:15 - 00:11:41:19 with most stem cells 00:11:41:19 - 00:11:43:16 in the bone marrow. Really? Fascinating. 00:11:43:16 - 00:11:45:03 Pelvic bones have the most stem 00:11:45:03 - 00:11:45:14 cells. Right. 00:11:45:14 - 00:11:48:03 Look at that fun nugget. 00:11:48:03 - 00:11:50:19 How long is the patient hospitalized? 00:11:50:19 - 00:11:52:14 Patients usually are hospitalized 00:11:52:14 - 00:11:53:22 for about three weeks, 00:11:53:22 - 00:11:54:21 a little bit less 00:11:54:21 - 00:11:56:12 for an autologous transplant 00:11:56:12 - 00:11:58:13 and a little bit more 00:11:58:13 - 00:11:59:14 close to four weeks 00:11:59:14 - 00:12:01:21 for an allogeneic transplant. Okay. 00:12:01:21 - 00:12:04:06 And then once they go home, you know, 00:12:04:06 - 00:12:05:01 what's life 00:12:05:01 - 00:12:06:01 looking like when you go home? 00:12:06:01 - 00:12:07:13 So after they immediately 00:12:07:13 - 00:12:09:03 after they get discharged, 00:12:09:03 - 00:12:09:21 they come 00:12:09:21 - 00:12:11:01 very frequently 00:12:11:01 - 00:12:12:09 to the outpatient, 00:12:12:09 - 00:12:12:18 to the 00:12:12:18 - 00:12:14:11 an infusion center 00:12:14:11 - 00:12:15:20 to be monitored 00:12:15:20 - 00:12:17:10 because they're by the time 00:12:17:10 - 00:12:18:02 they are discharged, 00:12:18:02 - 00:12:20:11 the counts are just starting 00:12:20:11 - 00:12:21:12 to come back up. 00:12:21:12 - 00:12:24:06 As I mentioned before, the blood counts 00:12:24:06 - 00:12:26:08 will drop significant 00:12:26:08 - 00:12:27:13 to very low levels 00:12:27:13 - 00:12:28:20 during hospitalization. 00:12:28:20 - 00:12:30:09 And when the blood counts 00:12:30:09 - 00:12:32:16 are starting to come back up, 00:12:32:16 - 00:12:34:21 they are not fully up. 00:12:34:21 - 00:12:35:17 They are not normal. 00:12:35:17 - 00:12:37:07 They just start to come back up. 00:12:37:07 - 00:12:39:23 So they need to monitor patients 00:12:39:23 - 00:12:43:11 initially daily in the outpatient 00:12:44:07 - 00:12:47:07 area for a blood count recovery, 00:12:47:07 - 00:12:49:12 a need for blood products, 00:12:49:12 - 00:12:51:09 growth factors. 00:12:51:09 - 00:12:52:01 For how long? 00:12:52:01 - 00:12:52:14 When you say 00:12:52:14 - 00:12:54:21 daily, but like over over what time span? 00:12:54:21 - 00:12:56:18 Well, they usually 00:12:56:18 - 00:12:59:08 it takes probably a few weeks less 00:12:59:08 - 00:13:01:17 for an autologous transplant, a few more weeks 00:13:01:17 - 00:13:03:11 for allogeneic transplant - daily. 00:13:03:11 - 00:13:05:11 And then we space out the visits 00:13:05:11 - 00:13:07:06 as we see that patient is doing well. 00:13:07:06 - 00:13:08:20 Doesn't need to really be 00:13:08:20 - 00:13:11:05 every day in the infusion center. Right. 00:13:11:05 - 00:13:12:02 What indicators 00:13:12:02 - 00:13:13:17 do you get that 00:13:13:17 - 00:13:14:21 that what you've done 00:13:14:21 - 00:13:16:04 is working... Effective? 00:13:16:04 - 00:13:17:16 Yeah. It's a good question. 00:13:17:16 - 00:13:20:00 So early after transplant 00:13:20:00 - 00:13:21:16 we start to do what we call 00:13:21:16 - 00:13:23:07 we look at the disease. 00:13:23:07 - 00:13:25:06 For patients with lymphoma 00:13:25:06 - 00:13:26:03 for example, 00:13:26:03 - 00:13:26:12 we look 00:13:26:12 - 00:13:27:09 at their lymph nodes 00:13:27:09 - 00:13:30:11 with scans. With a PET scan or CT scans. 00:13:30:13 - 00:13:32:02 For patients with leukemia. 00:13:32:02 - 00:13:33:14 That is primarily the bone marrow. 00:13:33:14 - 00:13:35:03 We do bone marrow biopsies 00:13:35:03 - 00:13:36:04 at regular intervals. 00:13:36:04 - 00:13:38:23 So these evaluations start at one month 00:13:38:23 - 00:13:40:01 after transplant, 00:13:40:01 - 00:13:41:23 then continue three months, six months, 00:13:41:23 - 00:13:43:15 a year at the minimum. 00:13:43:15 - 00:13:44:22 And I've had friends 00:13:44:22 - 00:13:46:08 that have have battled, 00:13:46:08 - 00:13:47:00 you know, certain things. 00:13:47:00 - 00:13:49:01 And they talk about that scansiety. 00:13:49:01 - 00:13:50:13 They get anxious on scan days. 00:13:50:13 - 00:13:51:04 And that's what you're 00:13:51:04 - 00:13:51:16 referring to, right? 00:13:51:16 - 00:13:52:14 The scans and you compare. 00:13:52:14 - 00:13:53:06 You just compare. 00:13:53:06 - 00:13:54:06 Right. Right, right, right. Exactly. 00:13:54:06 - 00:13:55:09 And you can tell if it's working. 00:13:55:09 - 00:13:57:08 What other types of 00:13:57:08 - 00:13:58:23 of cellular therapies 00:13:58:23 - 00:14:00:19 do you guys do at UCI Health? 00:14:00:19 - 00:14:02:23 Well, we rarely do what we call 00:14:02:23 - 00:14:03:10 a donor 00:14:03:10 - 00:14:04:18 lymphocyte infusion, 00:14:04:18 - 00:14:05:19 which is a procedure 00:14:05:19 - 00:14:08:06 in which we collect lymphocytes 00:14:08:06 - 00:14:09:06 from a donor, 00:14:09:06 - 00:14:10:22 from the donor of transplant 00:14:10:22 - 00:14:14:06 donor and infuse to the recipient 00:14:14:06 - 00:14:15:02 for a reason. 00:14:15:02 - 00:14:15:19 For example, 00:14:15:19 - 00:14:18:15 we see sometimes an early relapse 00:14:18:15 - 00:14:19:14 or indication 00:14:19:14 - 00:14:21:04 that the patient might relapse. 00:14:21:04 - 00:14:22:16 So we've done this recently 00:14:22:16 - 00:14:23:17 for a patient. 00:14:23:17 - 00:14:27:11 We ask the donor to come back to collect 00:14:27:11 - 00:14:28:20 only lymphocytes, 00:14:28:20 - 00:14:29:19 not stem cells, 00:14:29:19 - 00:14:31:18 just lymphocytes from one's blood, 00:14:31:18 - 00:14:34:05 and infuse them to the recipient 00:14:34:05 - 00:14:35:07 to try to 00:14:35:07 - 00:14:38:18 to get a stronger anti-tumor effect, 00:14:38:19 - 00:14:39:22 also called graft 00:14:39:22 - 00:14:41:21 versus lymphoma, graft versus 00:14:41:21 - 00:14:43:22 leukemia effect. Okay. 00:14:43:22 - 00:14:46:01 We want to do other cells in the future 00:14:46:01 - 00:14:47:19 where we want to do 00:14:47:19 - 00:14:48:17 natural infusion 00:14:48:17 - 00:14:51:17 of natural killer cells from a donor. 00:14:52:04 - 00:14:54:08 We also are interested to infuse 00:14:54:08 - 00:14:57:19 other cells, like modified T cells 00:14:57:19 - 00:15:00:19 to recognize certain viruses, 00:15:00:21 - 00:15:03:15 called viral specific T cells, to 00:15:03:15 - 00:15:04:18 to treat patients 00:15:04:18 - 00:15:06:05 with a viral illness 00:15:06:05 - 00:15:07:00 that otherwise 00:15:07:00 - 00:15:10:03 maybe may not have medical... may not have... 00:15:10:13 - 00:15:11:13 Yeah. 00:15:11:13 - 00:15:12:13 Drug treatments 00:15:12:13 - 00:15:14:18 or is refractory to drug therapy. 00:15:14:18 - 00:15:17:04 Do you run into a lot of 00:15:17:04 - 00:15:18:08 a lot of like red tape 00:15:18:08 - 00:15:19:11 with with what you're doing. 00:15:19:11 - 00:15:20:08 Because I feel like it's 00:15:20:08 - 00:15:21:22 kind of a it's a very cutting edge thing. 00:15:21:22 - 00:15:22:20 Are people skeptical 00:15:22:20 - 00:15:23:20 of what you're doing? 00:15:23:20 - 00:15:25:10 No, I don't think so. 00:15:25:10 - 00:15:27:07 No, we don't have 00:15:27:07 - 00:15:27:16 I mean, 00:15:27:16 - 00:15:30:16 we we obviously do everything either. 00:15:30:17 - 00:15:31:13 That is novel 00:15:31:13 - 00:15:33:06 has to be on a clinical trial. 00:15:33:06 - 00:15:35:01 Sure. Or or. 00:15:37:12 - 00:15:39:13 Or it's standard procedure. 00:15:39:13 - 00:15:42:01 And we really don't have 00:15:42:01 - 00:15:43:04 this type of issues. 00:15:43:04 - 00:15:44:12 One of the places I hear about stem 00:15:44:12 - 00:15:45:15 cells is like, 00:15:45:15 - 00:15:47:16 you'll hear of athletes who, you know, 00:15:47:16 - 00:15:48:22 their knees are shot or whatever, 00:15:48:22 - 00:15:49:14 and they get 00:15:49:14 - 00:15:51:01 they get a hip replacement or whatever. 00:15:51:01 - 00:15:51:12 And they'll, 00:15:51:12 - 00:15:53:09 they'll do like stem cell treatment. 00:15:53:09 - 00:15:53:23 Is that 00:15:53:23 - 00:15:55:17 is that good or is that good for them? 00:15:55:17 - 00:15:57:16 I hear about it in that context. 00:15:57:16 - 00:15:59:15 This is an unproven therapy. 00:15:59:15 - 00:16:00:08 That's what I thought. 00:16:00:08 - 00:16:02:04 And it's it's not 00:16:02:04 - 00:16:04:06 there are no studies that I'm aware of. 00:16:04:06 - 00:16:05:18 And in general, 00:16:05:18 - 00:16:07:03 I cannot recommend 00:16:07:03 - 00:16:08:21 these type of therapies 00:16:08:21 - 00:16:11:03 because they've not been studied 00:16:11:03 - 00:16:12:06 systematically. 00:16:12:06 - 00:16:15:07 And... to know the efficacy of this. 00:16:15:08 - 00:16:15:23 Yes. 00:16:15:23 - 00:16:17:00 And you're only dealing 00:16:17:00 - 00:16:18:19 in the things that you know are. 00:16:18:19 - 00:16:20:04 Working or approved. 00:16:20:04 - 00:16:22:04 How do we tell, 00:16:22:04 - 00:16:24:22 you know, the legitimate from the fake. 00:16:24:22 - 00:16:26:05 In general, 00:16:26:05 - 00:16:27:19 valid procedure 00:16:27:19 - 00:16:30:03 should be approved by the FDA. 00:16:30:03 - 00:16:31:17 And it's, 00:16:31:17 - 00:16:32:03 you know, 00:16:32:03 - 00:16:32:16 it's used 00:16:32:16 - 00:16:34:12 as the standard of care procedure. 00:16:34:12 - 00:16:37:13 So if if not approved and not studied, 00:16:37:13 - 00:16:41:03 I don't think it's... I think any procedure 00:16:41:04 - 00:16:42:05 should either be on 00:16:42:05 - 00:16:45:00 an investigational trial or 00:16:46:09 - 00:16:47:15 if has gone already through 00:16:47:15 - 00:16:48:14 the process 00:16:48:14 - 00:16:50:15 has FDA approval and it can be 00:16:50:15 - 00:16:51:15 can be used... 00:16:51:15 - 00:16:52:05 Like if your neighbor 00:16:52:05 - 00:16:53:00 is trying to sell you 00:16:53:00 - 00:16:54:04 some stem cells on Facebook, 00:16:54:04 - 00:16:55:22 it's probably. Not not a good idea. 00:16:55:22 - 00:16:57:17 I... Don't buy that. Yeah. Okay. Thought so. 00:16:57:17 - 00:17:01:06 So what sets, you know, UCI 00:17:01:06 - 00:17:03:18 Health apart from from anywhere else 00:17:03:18 - 00:17:05:07 really in Southern California 00:17:05:07 - 00:17:07:14 or as far as you can see? Right. 00:17:07:14 - 00:17:09:21 So we have some unique approaches 00:17:09:21 - 00:17:11:00 to what we do. 00:17:11:00 - 00:17:14:21 One of them is to prevent one of the main 00:17:14:21 - 00:17:16:03 complications of transplantation 00:17:16:03 - 00:17:18:04 called graver versus host disease. 00:17:18:04 - 00:17:19:15 Say it one more time what's it called? 00:17:19:15 - 00:17:21:10 Graft versus host disease. 00:17:21:10 - 00:17:23:14 So graft versus host disease. Got it. 00:17:23:14 - 00:17:25:13 This disease is caused by the donor 00:17:25:13 - 00:17:27:01 cells in the allogeneic 00:17:27:01 - 00:17:28:08 transplant setting. 00:17:28:08 - 00:17:30:04 When you infuse the donor cells, 00:17:30:04 - 00:17:31:17 sometimes the donor cells 00:17:31:17 - 00:17:35:08 can react against the recipient's body. 00:17:35:08 - 00:17:38:17 And we try to prevent this. This can be... Severe 00:17:38:17 - 00:17:39:22 forms of graft vs host 00:17:39:22 - 00:17:42:03 disease can be life threatening. 00:17:42:03 - 00:17:45:09 So one of the main goals is to prevent 00:17:45:09 - 00:17:48:15 this life threatening complication. 00:17:49:11 - 00:17:52:18 Another approach which is unique to UCI 00:17:52:18 - 00:17:53:23 and we have an ongoing 00:17:53:23 - 00:17:54:18 clinical trial, 00:17:54:18 - 00:17:56:07 is to customize 00:17:56:07 - 00:17:57:21 the conditioning regimen, 00:17:57:21 - 00:17:59:12 which is the chemotherapy part 00:17:59:12 - 00:18:02:22 of the transplant, to tailor to receive 00:18:03:02 - 00:18:06:02 to the recipient and to the disease. 00:18:06:03 - 00:18:08:03 So we say that we are 00:18:09:04 - 00:18:11:11 modifying the the 00:18:11:11 - 00:18:14:10 chemotherapy based on one's disease 00:18:14:10 - 00:18:15:23 and disease 00:18:15:23 - 00:18:16:22 characteristics 00:18:16:22 - 00:18:18:23 and patient's characteristics, 00:18:18:23 - 00:18:20:06 because obviously patients 00:18:20:06 - 00:18:21:02 are very different 00:18:21:02 - 00:18:22:21 from 19 year 00:18:22:21 - 00:18:25:17 old with leukemia to a 75 year old 00:18:25:17 - 00:18:26:14 with leukemia. 00:18:26:14 - 00:18:29:00 So these people are going to, you know, 00:18:29:00 - 00:18:29:15 they cannot 00:18:29:15 - 00:18:31:15 tolerate the same conditioning 00:18:31:15 - 00:18:33:01 and same intensity 00:18:33:01 - 00:18:34:17 of chemotherapy, for example. 00:18:34:17 - 00:18:37:23 But taking to one step forward 00:18:38:00 - 00:18:41:04 is to also take into consideration 00:18:41:05 - 00:18:42:06 the risk of disease. 00:18:42:06 - 00:18:43:00 I mentioned 00:18:43:00 - 00:18:45:08 there's no one acute myeloid leukemia. 00:18:45:08 - 00:18:46:17 There are many forms of leukemia 00:18:46:17 - 00:18:47:17 with different risks. 00:18:47:17 - 00:18:50:10 So we want to incorporate all these 00:18:50:10 - 00:18:54:08 in an algorithm to maximize transplant 00:18:54:08 - 00:18:55:04 outcomes. Okay. 00:18:55:04 - 00:18:56:12 So we were talking about the 00:18:56:12 - 00:18:59:05 how you know if if it's effective, right. 00:18:59:05 - 00:19:00:14 If it's working in somebody. 00:19:00:14 - 00:19:03:14 If you see that it's not are 00:19:03:14 - 00:19:05:16 you able to course correct and go, 00:19:05:16 - 00:19:07:06 well let me let me try it again 00:19:07:06 - 00:19:07:23 or do this. 00:19:07:23 - 00:19:10:20 Like if it doesn't work once, 00:19:10:20 - 00:19:12:08 does that mean it doesn't work 00:19:12:08 - 00:19:13:12 always in this person 00:19:13:12 - 00:19:14:12 or do you just come at it 00:19:14:12 - 00:19:15:14 from a different angle? 00:19:15:14 - 00:19:16:20 That's a great question. 00:19:16:20 - 00:19:19:03 And it really depends again 00:19:19:03 - 00:19:21:03 on the clinical situation. 00:19:21:03 - 00:19:25:00 But one example is if somebody fails 00:19:25:01 - 00:19:26:09 an autologous transplant, 00:19:26:09 - 00:19:28:10 for example, with lymphoma, right. 00:19:28:10 - 00:19:29:23 If a patient has lymphoma, 00:19:29:23 - 00:19:32:20 we do autologous transplant. Relapses. 00:19:32:20 - 00:19:35:06 We made may give that patient 00:19:35:06 - 00:19:36:19 CAR T-cell therapy 00:19:36:19 - 00:19:38:13 or we may take that person 00:19:38:13 - 00:19:40:23 to an allogeneic transplant this time, 00:19:40:23 - 00:19:44:08 which is in addition to the autologous transplant 00:19:44:08 - 00:19:46:00 has this graft versus 00:19:46:00 - 00:19:47:12 lymphoma effect, 00:19:47:12 - 00:19:49:00 which is an immunologic effect 00:19:49:00 - 00:19:50:11 caused by the donor cells. 00:19:50:11 - 00:19:54:01 And that in itself can help 00:19:54:01 - 00:19:54:18 prevent disease 00:19:54:18 - 00:19:57:03 coming back the second time. 00:19:57:03 - 00:19:58:01 Just on a personal note, 00:19:58:01 - 00:19:59:05 because you're very knowledgeable, 00:19:59:05 - 00:20:00:10 do you just think about stem cells 00:20:00:10 - 00:20:02:03 all the time, or do you do stuff like 00:20:02:03 - 00:20:03:03 what do you like to do for fun? 00:20:03:03 - 00:20:05:05 Do you fish or like you watch sports? 00:20:05:05 - 00:20:06:02 Like, what's your thing? 00:20:06:02 - 00:20:08:04 I like photography, so. You do. 00:20:08:04 - 00:20:09:00 Yeah. That's awesome. 00:20:09:00 - 00:20:11:23 I will show you soon a book with 00:20:11:23 - 00:20:14:20 about 50... 50 00:20:14:20 - 00:20:17:19 photos from Orange... from around. 00:20:17:19 - 00:20:18:22 Oh, that's so cool. 00:20:18:22 - 00:20:20:14 That's awesome. I love that. 00:20:20:14 - 00:20:21:21 And just a quiz for the room. 00:20:21:21 - 00:20:22:23 What spot on our body 00:20:22:23 - 00:20:24:13 has the most stem cells? Pelvis. 00:20:24:13 - 00:20:24:23 That's it. 00:20:24:23 - 00:20:27:01 Good to go, guys. I'll buy you lunch. 00:20:27:01 - 00:20:27:18 What do you want 00:20:27:18 - 00:20:29:07 everyone to know about stem cells 00:20:29:07 - 00:20:32:04 as we sign off here? I think we need to. 00:20:32:04 - 00:20:35:05 I think we can extend this treatment 00:20:35:05 - 00:20:37:04 to patients with autoimmune diseases. 00:20:37:04 - 00:20:38:20 This is one of our one... 00:20:38:20 - 00:20:40:20 By the way of your question, 00:20:40:20 - 00:20:42:21 this is another interest of us. 00:20:42:21 - 00:20:47:19 I think this is actually a huge trend in 00:20:47:20 - 00:20:49:02 our field, 00:20:49:02 - 00:20:51:03 is a movement towards treating patients 00:20:51:03 - 00:20:54:17 with autoimmune diseases, with with 00:20:54:17 - 00:20:56:23 CAR-T therapy, but also 00:20:56:23 - 00:20:58:05 with autologous transplant. 00:20:58:05 - 00:20:59:17 So I really believe 00:20:59:17 - 00:21:00:18 that autologous 00:21:00:18 - 00:21:03:03 transplants can be extremely effective 00:21:03:03 - 00:21:06:02 in wiping out an autoimmune disease 00:21:06:02 - 00:21:08:08 because of this immunologic reset 00:21:08:08 - 00:21:10:15 that I mentioned before, 00:21:10:15 - 00:21:11:05 an immune 00:21:11:05 - 00:21:12:17 reset of a patient 00:21:12:17 - 00:21:14:05 with an autoimmune disease. 00:21:14:05 - 00:21:17:05 So we are really into 00:21:17:11 - 00:21:20:04 into providing the... in helping patients with 00:21:20:04 - 00:21:21:17 autoimmune diseases now. 00:21:21:17 - 00:21:23:10 And we have in fact an abstract 00:21:23:10 - 00:21:26:10 that we submitted to last 00:21:27:09 - 00:21:28:15 tandem meeting 00:21:28:15 - 00:21:31:22 American Society of Transplant Cell Therapy 00:21:31:22 - 00:21:34:08 meeting on approximately 00:21:34:08 - 00:21:36:00 25 patients 00:21:36:00 - 00:21:38:03 with different autoimmune diseases. 00:21:38:03 - 00:21:40:06 We transplanted with 00:21:40:06 - 00:21:41:16 we think very good success. 00:21:41:16 - 00:21:43:06 So we're talking what like M.S. 00:21:43:06 - 00:21:44:19 and lupus and things of that nature? 00:21:44:19 - 00:21:47:16 Exactly yeah. MS. 00:21:47:16 - 00:21:49:03 Stiff Persons Syndrome. 00:21:49:03 - 00:21:50:21 Oh yeah, the thing Celine Celine Dion has. 00:21:50:21 - 00:21:52:12 Yeah. 00:21:52:12 - 00:21:56:08 Yes, we're talking myasthenia gravis. 00:21:56:17 - 00:21:58:09 CIDP, 00:21:58:09 - 00:21:59:08 there's a 00:21:59:08 - 00:22:01:04 multitude of autoimmune diseases 00:22:01:04 - 00:22:03:11 that could potentially be treated with 00:22:03:11 - 00:22:05:10 with an autologous transplant. 00:22:05:10 - 00:22:06:03 As you're talking. 00:22:06:03 - 00:22:06:09 I'm sorry. 00:22:06:09 - 00:22:06:23 I'm just going to 00:22:06:23 - 00:22:08:17 maybe have another question or two. 00:22:08:17 - 00:22:10:23 Why do we call them stem cells? 00:22:10:23 - 00:22:11:12 What is the 00:22:11:12 - 00:22:13:01 what is the significance of the name. 00:22:13:01 - 00:22:14:13 Because the cells 00:22:14:13 - 00:22:16:06 these are as I mentioned, 00:22:16:06 - 00:22:18:07 they have certain characteristics 00:22:18:07 - 00:22:20:19 different than differentiated cells, 00:22:20:19 - 00:22:22:03 red blood cells, 00:22:22:03 - 00:22:23:20 white cells in the blood. 00:22:23:20 - 00:22:26:01 platelets are differentiated cells. 00:22:26:01 - 00:22:28:03 They have a certain lifespan, a lifespan. 00:22:28:03 - 00:22:29:23 And they are going to die 00:22:29:23 - 00:22:32:22 in a matter of days... OK... to few weeks. 00:22:32:22 - 00:22:35:14 Stem cells are quiescent cells. They’re. 00:22:35:14 - 00:22:38:02 They are not dividing cells. They are 00:22:39:05 - 00:22:40:18 residing in tissues 00:22:40:18 - 00:22:43:18 and they generate these. 00:22:43:21 - 00:22:46:12 There are some sort of 00:22:46:12 - 00:22:48:05 mother cells that 00:22:48:05 - 00:22:51:08 that would give rise to these cells, 00:22:51:08 - 00:22:52:14 that differentiate 00:22:52:14 - 00:22:54:07 the cells that do their function 00:22:54:07 - 00:22:56:21 and eventually are eliminated. 00:22:56:21 - 00:22:57:16 I want to talk 00:22:57:16 - 00:22:58:05 just a little bit 00:22:58:05 - 00:23:02:04 more about about who gets to be a donor. 00:23:02:06 - 00:23:04:10 How can how can someone be a stem 00:23:04:10 - 00:23:05:14 cell donor? Right. 00:23:05:14 - 00:23:07:14 So we're talking about donor 00:23:07:14 - 00:23:09:15 for allogeneic transplants. 00:23:09:15 - 00:23:13:06 Donor donors can be related or unrelated. 00:23:13:17 - 00:23:15:16 Related donors are family members. 00:23:15:16 - 00:23:19:06 Usually we look at brothers or sisters, 00:23:19:18 - 00:23:21:19 first degree relatives. 00:23:21:19 - 00:23:23:17 And we ideally 00:23:23:17 - 00:23:25:01 and this is how the field 00:23:25:01 - 00:23:26:08 evolve over time. 00:23:26:08 - 00:23:29:12 We wanted to look at what tissue match 00:23:29:12 - 00:23:32:12 or we call it HLA matching. 00:23:32:22 - 00:23:35:13 HLA system is a system of 12 markers 00:23:35:13 - 00:23:36:01 on surface 00:23:36:01 - 00:23:37:06 of the white cells 00:23:37:06 - 00:23:39:23 that we matched against. 00:23:39:23 - 00:23:41:10 So we want your markers 00:23:41:10 - 00:23:44:11 to be the same as the your donor’s marker. 00:23:44:16 - 00:23:47:15 This is called HLA compatibility. 00:23:47:15 - 00:23:49:02 And this in general 00:23:49:02 - 00:23:50:12 has been associated 00:23:50:12 - 00:23:52:10 historically with better 00:23:52:10 - 00:23:53:22 transplant outcomes. 00:23:53:22 - 00:23:57:04 So historically the better matching 00:23:57:06 - 00:23:59:02 the better outcomes. 00:23:59:02 - 00:24:02:22 Past ten plus years we have started to do 00:24:02:23 - 00:24:05:04 half match transplants, which 00:24:06:05 - 00:24:07:18 a recipient is matched with 00:24:07:18 - 00:24:11:12 the donor only had half of these markers. 00:24:11:12 - 00:24:14:12 And and outcomes we have shown recently. 00:24:14:13 - 00:24:15:23 Actually there is a paper 00:24:15:23 - 00:24:17:17 in a journal, Clinical Oncology 00:24:17:17 - 00:24:19:22 that we just published 00:24:19:22 - 00:24:23:21 showing that if you do not have an HLA 00:24:23:21 - 00:24:25:07 matched donor, 00:24:25:07 - 00:24:26:22 you may proceed to transplant 00:24:26:22 - 00:24:28:09 with half match donor. 00:24:28:09 - 00:24:30:02 And this has huge implications 00:24:30:02 - 00:24:33:17 because the number of matched donors 00:24:33:18 - 00:24:35:10 is about 25%. 00:24:35:10 - 00:24:37:15 So one has about 25% chance 00:24:37:15 - 00:24:40:15 to have an HLA match related donor. 00:24:41:07 - 00:24:43:16 In fact, you're much more likely 00:24:43:16 - 00:24:46:16 to have a half match, which is a 00:24:47:07 - 00:24:49:05 which is either a sibling 00:24:49:05 - 00:24:50:13 that is only half match, 00:24:50:13 - 00:24:52:11 not full match, or one of your children. 00:24:52:11 - 00:24:53:23 Or if you're a child, 00:24:53:23 - 00:24:56:03 one of your parents are for sure 00:24:56:03 - 00:24:56:18 half match. 00:24:56:18 - 00:24:57:22 So this extends 00:24:57:22 - 00:24:59:05 the donor pool 00:24:59:05 - 00:25:01:14 tremendously and is very important 00:25:01:14 - 00:25:04:22 for underdeveloped countries 00:25:04:22 - 00:25:08:04 because because they do not have access 00:25:08:04 - 00:25:09:11 to unrelated donors 00:25:09:11 - 00:25:10:14 or the registries 00:25:10:14 - 00:25:11:14 in other countries 00:25:11:14 - 00:25:14:20 like India, China, Pakistan, 00:25:14:20 - 00:25:15:07 and so 00:25:15:07 - 00:25:17:06 others is really 00:25:17:06 - 00:25:19:05 not so developed as United States. 00:25:19:05 - 00:25:21:02 So the likelihood of being able 00:25:21:02 - 00:25:22:08 to access a donor 00:25:22:08 - 00:25:26:07 from the registry is, is much lower. 00:25:26:07 - 00:25:27:16 So we rely a lot. 00:25:27:16 - 00:25:30:02 They rely a lot on half matched donors. 00:25:30:02 - 00:25:32:09 This has made a huge difference... Sure. 00:25:32:09 - 00:25:33:22 because in fact 00:25:33:22 - 00:25:36:06 we now can offer this procedure 00:25:36:06 - 00:25:39:06 to all those in need 00:25:39:17 - 00:25:42:11 as compared with, let's say, 20 years ago 00:25:42:11 - 00:25:45:04 when if you did not have an HLA 00:25:45:04 - 00:25:45:21 matched donor, 00:25:45:21 - 00:25:47:03 you did not get this and, 00:25:47:03 - 00:25:48:07 disease may come back 00:25:48:07 - 00:25:50:05 and we are not going to be able to save you. 00:25:50:05 - 00:25:51:10 You mentioned 00:25:51:10 - 00:25:52:04 CAR T-cells, 00:25:52:04 - 00:25:54:13 and I've heard that term from even, 00:25:54:13 - 00:25:55:15 like a different cancer events 00:25:55:15 - 00:25:56:00 I've hosted. 00:25:56:00 - 00:25:56:07 I've met 00:25:56:07 - 00:25:56:18 many people 00:25:56:18 - 00:25:58:11 that have have gone through CAR T-cell 00:25:58:11 - 00:25:59:09 therapy. 00:25:59:09 - 00:26:00:11 What can you explain 00:26:00:11 - 00:26:01:17 what CAR T cells are? 00:26:01:17 - 00:26:02:06 Right. 00:26:02:06 - 00:26:06:13 So CAR Ts are modified T cells with a CAR. 00:26:06:19 - 00:26:09:04 A CAR stands for a chimeric 00:26:09:04 - 00:26:10:18 antigen receptor. 00:26:10:18 - 00:26:13:21 This is just a marker, a receptor 00:26:13:23 - 00:26:17:15 that recognizes a two more antigen. 00:26:19:02 - 00:26:20:14 It basically this CAR 00:26:20:14 - 00:26:22:15 recognizes the cancer cell 00:26:22:15 - 00:26:27:02 and it's made its put in a in a recipient 00:26:27:03 - 00:26:27:23 T-cells 00:26:27:23 - 00:26:31:03 to direct the T-cells to the tumor. 00:26:31:03 - 00:26:34:03 So you simply direct 00:26:34:03 - 00:26:35:16 the immune system to 00:26:35:16 - 00:26:37:18 to the tumor to eliminate the tumor. 00:26:37:18 - 00:26:38:14 So it's like a car 00:26:38:14 - 00:26:39:08 like they're driving a. 00:26:39:08 - 00:26:40:17 CAR is like driving. 00:26:40:17 - 00:26:41:07 Go there. 00:26:41:07 - 00:26:43:19 Go to the tumor. Yes. Wow. Okay. 00:26:43:19 - 00:26:45:20 And then what are NK cells? 00:26:45:20 - 00:26:47:14 NK cells 00:26:47:14 - 00:26:50:07 in this case stands for natural killer cells. 00:26:50:07 - 00:26:53:18 Oh. These are actually specialized 00:26:53:18 - 00:26:57:21 cells, lymphoid cells from our blood. 00:26:57:21 - 00:26:59:08 Everybody has NK cells in their 00:26:59:08 - 00:27:02:08 blood that recognize malignantly 00:27:02:15 - 00:27:05:10 transformed cells or virally 00:27:05:10 - 00:27:07:17 infected cells and eliminate them. 00:27:07:17 - 00:27:09:06 So for example 00:27:09:06 - 00:27:10:18 you get a viral illness 00:27:10:18 - 00:27:11:21 respiratory illness. 00:27:11:21 - 00:27:13:15 It goes in your blood. 00:27:13:15 - 00:27:16:00 It may go into some of your cells but... 00:27:16:00 - 00:27:16:20 And they’re 00:27:16:20 - 00:27:18:05 if you if they are unchecked 00:27:18:05 - 00:27:19:23 they're going to kill you. 00:27:19:23 - 00:27:23:14 So these NK cells go after, recognize 00:27:23:14 - 00:27:25:06 these virally infected cells 00:27:25:06 - 00:27:29:04 or they recognize cells that are starting 00:27:29:04 - 00:27:32:05 to be transformed, malignantly. 00:27:32:15 - 00:27:36:04 They recognize them as non-self anymore 00:27:36:04 - 00:27:38:00 and then and eliminate them. 00:27:38:00 - 00:27:39:11 So this is 00:27:40:10 - 00:27:42:03 I believe that this is 00:27:42:03 - 00:27:43:19 there's an incredibly incredible 00:27:43:19 - 00:27:44:21 potential for 00:27:44:21 - 00:27:48:06 to to use these cells for therapeutic purposes. 00:27:48:06 - 00:27:51:22 And one major issue, I think, is 00:27:53:14 - 00:27:56:04 the fact that we do not have enough 00:27:56:04 - 00:27:56:23 of these cells 00:27:56:23 - 00:27:58:09 for therapeutic purposes, 00:27:58:09 - 00:28:00:02 and we are trying 00:28:00:02 - 00:28:01:19 to expand them in the lab 00:28:01:19 - 00:28:06:08 and infuse them to a patient with cancer. 00:28:06:09 - 00:28:06:16 Yes. 00:28:06:16 - 00:28:10:11 And there. It is... 00:28:11:00 - 00:28:13:13 they can be used in a broad 00:28:13:13 - 00:28:15:03 range of, of cancer 00:28:15:03 - 00:28:16:12 for therapeutic purposes. 00:28:16:12 - 00:28:19:05 So in terms of the autoimmune disease 00:28:19:05 - 00:28:20:03 what happens 00:28:20:03 - 00:28:22:04 what's occurring with this stem 00:28:22:04 - 00:28:24:19 cells to basically stop or arrest 00:28:24:19 - 00:28:26:03 something like an MS or... 00:28:26:03 - 00:28:28:00 So the main 00:28:28:00 - 00:28:29:12 that is a characteristic 00:28:29:12 - 00:28:29:23 of all 00:28:29:23 - 00:28:32:00 autoimmune diseases, which is 00:28:32:00 - 00:28:33:18 there are some 00:28:33:18 - 00:28:36:10 B cells, part of the immune system 00:28:36:10 - 00:28:37:15 that are generating 00:28:37:15 - 00:28:42:08 antibodies, that are misplaced. 00:28:42:08 - 00:28:44:05 Mistarget... that mistarget 00:28:44:05 - 00:28:45:10 different tissues 00:28:45:10 - 00:28:48:10 and organs in the body, for example, 00:28:49:05 - 00:28:50:03 MS. 00:28:50:03 - 00:28:52:01 In MS. 00:28:52:01 - 00:28:54:19 it is believed MS is caused by... 00:28:57:00 - 00:29:01:12 By antibodies against the general 00:29:01:15 - 00:29:03:16 after for example, 00:29:03:16 - 00:29:06:14 an infectious monoclonal an EBV 00:29:06:14 - 00:29:09:03 Epstein-Barr virus generates 00:29:09:03 - 00:29:12:09 an immune response from someone that 00:29:12:10 - 00:29:13:21 in most of the time 00:29:13:21 - 00:29:16:02 the aim is to eliminate the virus, 00:29:16:02 - 00:29:17:11 but through 00:29:17:11 - 00:29:18:03 a process 00:29:18:03 - 00:29:21:03 called molecular mimicry targets 00:29:21:20 - 00:29:24:20 some. 00:29:25:01 - 00:29:28:01 Tissues that in the 00:29:28:07 - 00:29:31:07 in the central nervous system, 00:29:31:10 - 00:29:34:09 causing the MS, causing destruction of 00:29:34:11 - 00:29:35:19 causing neural damage 00:29:35:19 - 00:29:38:19 and patchy typical patchy 00:29:39:16 - 00:29:42:06 demyelinating lesions that cause 00:29:42:06 - 00:29:43:01 nerve damage 00:29:43:01 - 00:29:44:21 and progressive debilitation MS. 00:29:44:21 - 00:29:47:21 So what I'm trying to say is 00:29:47:22 - 00:29:50:16 in autoimmune diseases in general, 00:29:50:16 - 00:29:53:19 there are antibodies of different types 00:29:53:19 - 00:29:54:16 that generate 00:29:54:16 - 00:29:56:00 different disease, for example. 00:29:56:00 - 00:29:58:18 Another example is in diabetes. 00:29:58:18 - 00:29:59:18 In type one diabetes 00:29:59:18 - 00:30:00:02 there are 00:30:00:02 - 00:30:03:15 antibodies against pancreatic cells. In 00:30:04:22 - 00:30:07:06 in autoimmune thyroiditis 00:30:07:06 - 00:30:09:22 there are antibodies against 00:30:09:22 - 00:30:11:01 thyroid tissue. 00:30:11:01 - 00:30:12:07 What we're trying to do 00:30:12:07 - 00:30:14:02 is with an autologous transplant 00:30:14:02 - 00:30:18:15 is to stop this immune attack, 00:30:19:07 - 00:30:21:19 eliminate the cells that cause 00:30:21:19 - 00:30:23:07 these antibodies. 00:30:23:07 - 00:30:25:10 The immune system will recover 00:30:25:10 - 00:30:29:11 without these B cells that generate 00:30:29:11 - 00:30:30:23 these antibodies 00:30:30:23 - 00:30:32:17 that are causing the disease. 00:30:32:17 - 00:30:34:10 The problem we find 00:30:34:10 - 00:30:37:14 is that in some cases, 00:30:37:15 - 00:30:40:01 there is irreversible damage 00:30:40:01 - 00:30:41:14 that has already occurred. 00:30:41:14 - 00:30:43:19 That's why intuitively makes 00:30:43:19 - 00:30:47:13 sense to act early and stop... 00:30:48:15 - 00:30:51:02 Stop the autoimmune attack 00:30:51:02 - 00:30:53:03 early in the course of the disease 00:30:53:03 - 00:30:55:08 to prevent organ damage. 00:30:55:08 - 00:30:56:09 Okay. 00:30:56:09 - 00:30:58:21 We for example, in MS, 00:30:58:21 - 00:31:01:19 if one has progressed 00:31:01:19 - 00:31:04:02 to a certain degree of debilitation 00:31:04:02 - 00:31:05:13 through extensive 00:31:05:13 - 00:31:07:11 plaque burden, for example, 00:31:07:11 - 00:31:08:18 it's very difficult to 00:31:08:18 - 00:31:10:17 to to reverse this 00:31:10:17 - 00:31:11:22 with an autologous transplant. 00:31:11:22 - 00:31:16:09 So the goal is to stop this 00:31:16:16 - 00:31:19:23 autoimmune attack early on and eliminate 00:31:19:23 - 00:31:20:18 these antibodies, 00:31:20:18 - 00:31:22:10 plus the cells that are producing 00:31:22:10 - 00:31:23:04 these antibodies. 00:31:23:04 - 00:31:25:12 I just came up with a little acronym 00:31:25:12 - 00:31:28:12 here: Simply The Expert Man - STEM. 00:31:29:07 - 00:31:30:22 That's this guy right here. 00:31:30:22 - 00:31:32:03 Thank you doctor. Thank you so much.
