Podcasts about hematopoietic

Commentary by Dr. Oscar Calvillo-Argüelles.

Welcome to the second installment of an exclusive 8-part ASTCT Talks series, supported by an educational grant from Sanofi US. In this series, ASTCT President Dr. Corey Cutler speaks with authors from each article in the latest Graft versus Host Disease and Late Effects Following Allogeneic Transplantation Journal collection. In this episode, Dr. Cutler is joined by Dr. Nathaniel S. Treister, a recognized expert in oral medicine, to discuss the intricacies of oral chronic GVHD and its impact on oral health following allogeneic hematopoietic cell transplantation. They explore the diagnostic criteria, effective management strategies, and long-term care considerations for patients, highlighting the importance of both supportive care and multidisciplinary collaboration. For further insights, read Dr. Treister's article, “Oral Chronic Graft-versus-Host Disease and Oral Health after Allogeneic Hematopoietic Cell Transplantation — What the Care Team Needs to Know”, and stay tuned as Dr. Cutler and authors continue to provide a comprehensive guide on cGVHD management through this supplement series.

n this episode, CJ dives deep into the powerful concept of neuroplasticity, the brain's ability to rewire itself and adapt through learning and experience. Neuroplasticity is not just a buzzword; it's a fundamental aspect of how we can improve cognitive performance, longevity, and overall health. CJ ties together biohacking, natural methods, and cutting-edge scientific discoveries to show how we can boost brain function, stave off aging, and optimize our physical health.Key Topics Covered:Cognitive Hacking: Improving focus, memory, creativity, and decision-making are all linked to keeping our brains flexible and sharp. CJ emphasizes that cognitive function directly impacts longevity, and brain health is a gateway to a longer, healthier life.Nootropics: CJ explores nootropics like Modafinil and its refined version, Armodafinil, as smart drugs that boost brain performance, alongside natural alternatives like cold exposure and breathing techniques, such as the Wim Hof Method.Natural Cognitive Boosters: From blueberries and dark leafy greens to mindfulness meditation, CJ offers accessible ways to keep your brain sharp without relying on synthetic compounds.Stem Cells and Aging: CJ breaks down the types of stem cells (e.g., Mesenchymal and Hematopoietic) and how they play a key role in repairing tissue and boosting the immune system. He suggests simple lifestyle changes like resistance training and intermittent fasting to naturally promote stem cell health.Muscle Growth and Anti-Aging: Maintaining muscle mass is crucial as we age. Strength training and anti-inflammatory diets rich in omega-3s can help slow down muscle degradation, while exploring the potential of follistatin for future anti-aging breakthroughs.Telomeres and Longevity: Stress management is essential for protecting telomeres, the protective caps on our DNA that shorten as we age. Practices like meditation, yoga, and spending time in nature can reduce stress and support longevity.Key Takeaways:Neuroplasticity is vital for keeping our brains flexible, and by learning new skills and habits, we keep our cognitive function sharp as we age.Natural cognitive enhancers like sleep, cold exposure, and mindfulness can be as effective as nootropics in boosting brain performance.Stem cell health can be maintained through regular exercise and intermittent fasting, which helps to boost immune function and tissue repair.Muscle maintenance is crucial for longevity; resistance training and anti-inflammatory foods can slow muscle loss and reduce inflammation.Telomere health is directly linked to stress. Reducing chronic stress through mindful practices helps protect your DNA and slow aging.5 Things You Can Start Doing Today:Practice mindfulness meditation to boost creativity, reduce stress, and support brain function.Incorporate berries and leafy greens into your diet to enhance memory and brain health.Start intermittent fasting to regenerate stem cells and improve longevity.Do strength training to maintain muscle mass and slow down the aging process.Prioritize sleep to enhance cognitive function and protect your overall health.Stay curious, and embrace a balanced approach to biohacking for a healthier, longer life!

Hematopoietic progenitor cell (HPC) transplant continues to be used in more and more situations. In this episode, Dr. Brian Adkins outlines the many issues surrounding transfusion support in HPC transplant patients (yes, including the challenge of ABO-incompatible HPC transplants!).

If you've studied the hematopoietic system malignancies—all the leukemias, lymphomas, and plasma cell disorders—you probably feel like you've been hit with the good old medical school fire hose. Now's a good time to take a step back from all the details, make sure that you remember the underlying framework, and pull together some information that connects several different diseases. In this brick, we'll revisit some of the hematopoietic diseases that we often talk about in pairs: acute vs chronic leukemias, benign lymph node diseases vs lymphoma, and low-grade vs high-grade lymphomas. Also, in case you haven't already done this on your own, we'll pull together all the important translocations, their respective diseases, and the reasons why we should remember them. After listening to this AudioBrick, you should be able to: Compare and contrast acute and chronic leukemias. Compare and contrast the morphologic features of benign follicular hyperplasia and follicular lymphoma. Compare and contrast the morphologic and clinical features of low-grade and high-grade lymphomas and give examples of each. Know the following translocations and name the disease (and prognostic significance, if any) associated with each: t(8;21), t(15;17), inv(16), 11q23, FLT3 mutation, t(9;22), t(11;14), t(14;18), and t(8;14).

“I think the most amazing thing we see is the softening of the skin, which can occur during the first two weeks of the conditioning regimen. The nurses on the floor see it, and I think it's just a tremendous gratification for them to see the results of something right before your eyes,” Tanya Helms, PA-C, from the division of hematological malignancies and cellular therapy at Duke University Medical Center in Durham, NC, told Lenise Taylor, MN, RN, AOCNS®, BMTCN®, oncology clinical specialist at ONS, during a discussion about what oncology nurses should know about transplantation for patients with non-oncologic conditions such as autoimmune disease, how the transplant process differs for non-oncology indications, and the clinical pearls oncology nurses should consider when caring for patients with autoimmune diseases during the transplantation process.  You can earn free NCPD contact hours after listening to this episode and completing the evaluation linked below.   Music Credit: “Fireflies and Stardust” by Kevin MacLeod  Licensed under Creative Commons by Attribution 3.0  Earn 0.5 NCPD contact hours of nursing continuing professional development (NCPD), which may be applied to the early post-transplant management and education, treatment modalities, diagnosis, staging and treatment planning, or coordination of care ILNA category, by listening to the full recording and completing an evaluation at myoutcomes.ons.org by September 29, 2025.

This targets all the areas where the immune effector cells live. We also use CD34 selection, which is a process that separates CD34-positive cells from the stem cell product that's collected prior to transplant, to eliminate the possibility of reinfusing activated immune cells back into the patients.” TS 3:18  “For patients with diffuse scleroderma, you want to offer transplant when they have evidence of significant disease, but they're not so compromised that they can't tolerate or have increased risk of complications from the conditioning regimen. Understanding the patient's rate of disease progression is key when determining to transplant.” TS 6:45  “When a patient is referred, we call the patient, and we talk about how the transplant conditioning regimen works to reset the immune system and stop disease progression. We explain the workup visit and go over an example of the timeline needed to collect the cells, admit to the hospital for conditioning, and the recovery process as an outpatient. We want patients to understand the big picture before they ever come to Duke.” TS 7:57  “Some patients come to us significantly disabled by their scleroderma. They may be in a wheelchair, so they require special vehicles for travel. Patients whose hands are severely involved need assistance with their ADLs [activities of daily living].” TS 11:43  “There have been three clinical trials that show autologous transplant improves event-free survival and overall survival and has been shown to decrease all-cause mortality. But it does not repair damaged gastrointestinal, pulmonary, or cardiac tissue. Any fibrosis that has happened is permanent.” TS 12:22  “The most amazing thing we see is the softening of the skin, which can occur during the first two weeks of the conditioning regimen. The nurses on the floor see it, and I think it's just a tremendous gratification for them to see the results of something right before your eyes.” TS 13:01  “Social media has been a huge contributor towards patient self-referrals. Patients are telling their stories on Facebook; patients are asking other questions about how to get referred to a transplant center; and patients whose rheumatologists have not referred them will seek out transplant centers to learn more about transplant for scleroderma.” TS 13:48  “For people with hematologic malignancies, it's all about getting that patient to remission and then transplanting them. . . . These patients have experienced chemotherapy and the adverse effects. They know about low blood counts and fatigue and recovery. They know about central lines and transfusions. The scleroderma patients come to transplantation with progressive disease. They've typically not had blood transfusions, but they are now going to receive total body radiation, chemotherapy, and a stem cell transplant over the next six weeks. And it can be overwhelming. . . . Every day is something new for them to process and learn.” TS 14:56  “Patients become pancytopenic, and they are heavily immunosuppressed. They are on steroids during the conditioning regimen to prevent scleroderma flares during conditioning. These patients have a central line so monitoring for infections, such as assessing vital signs for signs and symptoms of infection, and being aware that steroids can mask a fever.” TS 16:49   

Welcome to Living Well with MS, where we are pleased to welcome Professor Richard Burt as our guest! Professor Burt is a leading expert in hematopoietic stem cell transplantation (HSCT) for autoimmune diseases including MS and has been awarded a number of prestigious accolades. Watch this episode on YouTube here. Keep reading for the key episode takeaways and Professor Burt's bio. Questions and Timestamps 02:35 Could you introduce yourself and tell us about your work with patients with autoimmune conditions and MS? 12:03 What do you think about the idea of flipping the model and offering the most aggressive treatment options to patients first? 16:27 What are the risks of HSCT? 21:18 Can you tell us about the costs associated with stem cell transplantation? 24:13 What type of patients respond best to HSCT? 31:16 Do you see a future where doctors are trained in multiple fields and understand the whole picture of autoimmunity? 38:10 If someone's interested in exploring HSCT, what should they look for in a clinic or physician? 41:47 HSCT has a high upfront cost but how does that compare to being on an MS drug for years or perhaps a lifetime? 53:50 The Dalai Lama wrote the introduction to your book 'Everyday Miracles'. How did that come about? Selected Key Takeaways Randomised controlled trial results for HSCT have been very positive 05:12 “In a randomised trial, [HSCT] was just hands down much better than any [other] drug. All the drugs you use for MS are based on approval for slowing disease activity. That is slowing the number of relapses or slowing the rate of progression of disability but not stopping it or not reversing it. Often you stay on these drugs indefinitely. A transplant, on the other hand, is a one-time treatment and afterwards, you get better, your neurologic disability reverses, nothing else had done that.” It's important to consider the disease trajectory, risks, and benefits of stem cell transplants. 14:02 “MS causes accelerated loss of brain volume, that is brain atrophy. Unfortunately, as we age, we get brain atrophy and a normal, very low, but normal decline. But once you get MS, that decline takes a much sharper drop, and you're losing neural function a lot faster than normal ageing. For some reason, that's not viewed as a sub-acute or semi-emergency situation that you want to reverse. Traditional drugs have mostly just slowed that rate of decline, but it's still faster than what happens with normal ageing. I would think a more aggressive approach up front would be wise, but you always have to remember [the] risk–benefit. If we could do a stem cell transplant with zero risk of mortality, I would say absolutely for everybody. But you can't do that right now.” A medical speciality and institute for autoimmunology could help push the field forward 34:20 “There are 80 different autoimmune diseases that I can think of offhand. They're all “homeless” in different departments like Crohn's disease [which is] in gastroenterology, Scleroderma [which] is in rheumatology, and multiple sclerosis [which] is in neurology. They're all separated [into] different areas. If there was a better organisation, beginning at a federal level with a national institute of autoimmune diseases that supports centres of excellence around the country, that would really help this go forward.” Want to learn more about living a full and happy life with multiple sclerosis?  Sign up to our newsletter to hear our latest tips.

Abstract: Age-associated clonal hematopoiesis (CH) occurs due to somatic mutations accrued in hematopoietic stem cells (HSCs) that confer a selective advantage in the context of aging. The mechanisms by which CH-mutant HSCs gain this advantage with aging are not comprehensively understood. Using unbiased transcriptomic approaches, we identify Oncostatin M (OSM) signaling as a candidate contributor to aging-driven Dnmt3a-mutant CH. We find that Dnmt3a-mutant HSCs from young mice do not functionally respond to acute OSM stimulation with respect to proliferation, apoptosis, hematopoietic engraftment, or myeloid differentiation. However, young Dnmt3a-mutant HSCs transcriptionally upregulate an inflammatory cytokine network in response to acute OSM stimulation including genes encoding IL-6, IL-1{beta} and TNF. In addition, OSM-stimulated Dnmt3a-mutant HSCs upregulate the anti-inflammatory genes Socs3, Atf3 and Nr4a1, creating a negative feedback loop limiting sustained activation of the inflammatory network. In the context of an aged bone marrow (BM) microenvironment with chronically elevated levels of OSM, Dnmt3a-mutant HSCs upregulate pro-inflammatory genes but do not upregulate Socs3, Atf3 and Nr4a1. Together, our work suggests that chronic inflammation with aging exhausts the regulatory mechanisms in young CH-mutant HSCs that resolve inflammatory states, and that OSM is a master regulator of an inflammatory network that contributes to age-associated CH.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.06.29.547089v1?rss=1 Authors: Araki, D., Chen, V., Redekar, N., Salisbury-Ruf, C., Luo, Y., Liu, P., Li, Y., Smith, R., Dagur, P., Combs, C., Larochelle, A. Abstract: Granulocyte colony stimulating factor (G-CSF) is commonly used as adjunct treatment to hasten recovery from neutropenia following chemotherapy and autologous transplantation of hematopoietic stem and progenitor cells (HSPCs) for malignant disorders. However, the utility of G-CSF administration after ex vivo gene therapy procedures targeting human HSPCs has not been thoroughly evaluated. Here, we provide evidence that post-transplant administration of G-CSF impedes engraftment of CRISPR-Cas9 gene edited human HSPCs in xenograft models. G-CSF acts by exacerbating the p53-mediated DNA damage response triggered by Cas9-mediated DNA double-stranded breaks. Transient p53 inhibition in culture attenuates the negative impact of G-CSF on gene edited HSPC function. In contrast, post-transplant administration of G-CSF does not impair the repopulating properties of unmanipulated human HSPCs or HSPCs genetically engineered by transduction with lentiviral vectors. The potential for post-transplant G-CSF administration to aggravate HSPC toxicity associated with CRISPR-Cas9 gene editing Cas9 should be considered in the design of ex vivo autologous HSPC gene editing clinical trials.

In this week's episode, we will review patients with chronic ITP having clonal expansions of a specific subset of CD8 T cells, called terminally differentiated effector memory T cells, or TEMRA. Next, for patients with diffuse large B-cell lymphomas, use of a so-called dark-zone signature, previously referred to as the double-hit signature, could help refine prognosis. Finally on today's podcast we'll discuss rethinking the role of hematopoietic stem cells following physiologic emergencies such as acute inflammation and blood loss.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.04.27.538580v1?rss=1 Authors: Lee, S., Zhan, H. Abstract: Thrombopoietin (TPO) and its receptor MPL play crucial roles in hematopoietic stem cell (HSC) function and platelet production. However, the precise effects of TPO/MPL signaling on HSC regulation in different hematopoietic niches remain unclear. Here, we investigated the effects of TPO/MPL ablation on marrow and splenic hematopoiesis in TPO-/- and MPL-/- mice during aging. Despite severe thrombocytopenia, TPO-/- and MPL-/- mice did not develop marrow failure during a 2-year follow-up. Marrow and splenic HSCs exhibited different responses to TPO/MPL ablation and exogenous TPO treatment. Splenic niche cells compensated for marrow HSC loss in TPO-/- and MPL-/- mice by upregulating CXCL12 levels. These findings provide new insights into the complex regulation of HSCs by TPO/MPL and reveal a previously unknown link between TPO and CXCL12, two key growth factors for HSC maintenance. Understanding the distinct regulatory mechanisms between marrow and spleen hematopoiesis will help develop novel therapeutic approaches for hematopoietic disorders.

The Root Cause Medicine Podcast is created by Rupa Health, the best way to order, track & manage results from 30+ lab companies in one place for free. The Root Cause Medicine Podcast is a weekly one-on-one conversation with renowned medical experts, specialists, and pioneers who are influencing the way we look at our health and wellbeing. This week we're joined by Dr. Richard Burt, Chief of the Division of Immunotherapy, Department of Medicine, Feinberg School of Medicine, Northwestern University, Chicago, Illinois. In this episode, Dr. Richard Burt shares his insights on hematopoietic stem cell transplant (HSCT) for autoimmune disorders. For thirty-five years, Dr. Burt dedicated himself to advancing stem cell and cellular therapy, beginning with animal models and, later, some of the world's first clinical trials. He authored over 145 articles, mostly as the first author, and edited four medical textbooks. As the first Autoimmune Committee Chairperson for the International Bone Marrow Transplant Registry (IBMTR), he led the way in developing stem cell clinical trials for autoimmune diseases, securing a National Institute of Health (NIH) $10,000,000 multi-center contract. Dr. Burt performed America's first hematopoietic stem cell transplant (HSCT) for multiple sclerosis (MS), systemic lupus erythematosus (SLE), Crohn's disease (CD), stiff person syndrome (SPS), and chronic inflammatory demyelinating polyneuropathy (CIDP). He also published the world's first randomized clinical stem cell transplantation trials for systemic sclerosis and multiple sclerosis. Dr. Burt's pioneering stem cell work earned him recognition as one of the top 50 people in the world for improving humanity by Scientific American in 2006, along with A1 Gore and Steve Jobs. In 2011, Science Illustrated recognized his stem cell work as one of the top 10 advances of the decade. Key Takeaways: What is a hematopoietic stem cell transplant? Hematopoietic stem cell transplantation (HSCT) is a medical procedure where multipotent stem cells are transplanted into a patient, typically from bone marrow, peripheral blood, or umbilical cord blood. These cells can replicate and produce new, healthy blood cells, which can rejuvenate or repair damaged tissue in different organs, and also help fight viruses and foreign tissue. While leukemia is caused by defects in the blood stem cells themselves, autoimmune diseases arise from defects in the immune cells produced by these stem cells. To treat autoimmune diseases, specialists target the effector cells responsible for the disease and eliminate them, then quickly regenerate healthy cells from the blood stem cell. By using HSCT to replace damaged or defective cells with healthy ones, physicians hope to mitigate the symptoms of autoimmune disorders and promote long-term recovery. This innovative approach to treatment is still undergoing testing and refinement, but it shows great promise in the fight against these debilitating diseases. Finding the optimal transplant regimen for autoimmune diseases If your regimen is too strong, whether it's myeloablative or non-myeloablative, you can have more toxicity and problems. If it's too weak, it's not going to be effective. And so you've got to find that right regimen. When finding the optimal transplant regimen for autoimmune diseases, the aim is to develop a treatment plan that maximizes the benefits of the transplant while minimizing the risks and complications associated with it. An optimal transplant regimen for autoimmune diseases involves selecting the appropriate donor, considering the type of transplant, choosing the right conditioning regimen, and determining the timing and dosing of immunosuppressive medications. Financial toxicity in American healthcare systems Financial toxicity is a growing concern in America, particularly in medical treatments. Unfortunately, this often leads to patients being prescribed expensive treatments that may not be the best option for their specific needs. To achieve successful outcomes with hematopoietic stem cell transplantation, two key factors need to be considered: patient selection and the conditioning regimen used. However, due to the financial pressures facing healthcare providers and institutions, specialists may feel obligated to prescribe expensive treatments, even if they are not necessarily the most appropriate option for the patient. This can be a major source of frustration for patients, who may struggle to afford these treatments or may not receive the care that they truly need. Dr. Burt emphasizes the importance of physicians taking responsibility for their patient's care and being mindful of the financial implications of their recommendations. Rather than being driven solely by financial considerations, doctors should focus on providing the best possible care for their patients. By doing so, they can help to mitigate the effects of financial toxicity and ensure that patients receive the treatments that are best suited to their individual needs.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.03.20.533430v1?rss=1 Authors: Somuncular, E., Su, T.-Y., Dumral, O., Johansson, A.-S., Luc, S. Abstract: Hematopoiesis is maintained by hematopoietic stem cells (HSCs) that replenish the blood lineages throughout life. It is well-established that the HSC pool is functionally heterogeneous consisting of cells differing in longevity, self-renewal ability, cell proliferation, and lineage differentiation. Although HSCs can be identified through the Lin-Sca-1+c-Kit+CD48-CD34-CD150+ immunophenotype, the cell surface marker combination does not permit the absolute purification of functional HSCs with long-term (LT) reconstituting ability. Prospective isolation of LT HSCs is crucial for mechanistic understanding of the biological functions of HSCs, and for resolving the functional heterogeneity within the HSC population. Here, we show that the combination of CD229 and CD49b cell surface markers within the phenotypic HSC compartment identifies a subset of multipotent progenitor cells with high proliferative activity and short-term reconstituting ability. Thus, functional HSCs can be prospectively isolated by the addition of CD229 and CD49b to conventional HSC markers. Copy rights belong to original authors.

Abstract: Metabolic pathways are plastic and rapidly change in response to stress or perturbation. Current metabolic profiling techniques require lysis of many cells, complicating the tracking of metabolic changes over time after stress in rare cells such as hematopoietic stem cells (HSCs). Here, we aimed to identify the key metabolic enzymes that define metabolic differences between steady-state and stress conditions in HSCs and elucidate their regulatory mechanisms. Through quantitative 13C metabolic flux analysis of glucose metabolism using high-sensitivity glucose tracing and mathematical modeling, we found that HSCs activate the glycolytic rate-limiting enzyme phosphofructokinase (PFK) during proliferation and oxidative phosphorylation (OXPHOS) inhibition. Real-time measurement of adenosine triphosphate (ATP) levels in single HSCs demonstrated that proliferative stress or OXPHOS inhibition led to accelerated glycolysis via increased activity of PFKFB3, the enzyme regulating an allosteric PFK activator, within seconds to meet ATP requirements. Furthermore, varying stresses differentially activated PFKFB3 via PRMT1-dependent methylation during proliferative stress and via AMPK-dependent phosphorylation during OXPHOS inhibition. Overexpression of Pfkfb3 induced HSC proliferation and promoted differentiated cell production, whereas inhibition or loss of Pfkfb3 suppressed them. This study reveals the flexible and multilayered regulation of HSC metabolism to sustain hematopoiesis under stress and provides techniques to better understand the physiological metabolism of rare hematopoietic cells.

F., Oggier, A., De Leval, L., Nombela-Arrieta, C., Naveiras, O. Abstract: Hematopoietic Stem and Progenitor Cells (HSPCs) reside in the hematopoietic niche, a structure that regulates the balance of cellular quiescence, self-renewal and commitment in a demand-adapted manner. The bone marrow (BM) hematopoietic niche is formed by several cellular players, mainly endothelial cells, osteoblasts, adipocytes, and stromal cells. While the BM niche forms a complex structure, evidence exists for simpler, albeit functional, extramedullary hematopoietic niches. However, the composition of what constitutes the simplest unit of an HSPC supportive microenvironment remains largely unknown. Here, we show that the adult adrenal gland can be transformed into a hematopoietic supportive environment. Upon splenectomy and hormonal stimulation, the adult adrenal gland can be induced to recruit and host HSPC function, including serial transplantation. Furthermore, the adrenal stroma contains a CXCL12+ population, reminiscent of BM CXCL12-Abundant Reticular (CAR) cells. Mirroring this, we found CXCL12+ cells in patient samples obtained from a local cohort of myelolipoma, a benign adrenal tumor composed of adipose and hematopoietic tissue that constitutes the most common site of extramedullary hematopoiesis specific to the adult. We present our model as a novel tool to increase our understanding of the physiology of hematopoietic support and to facilitate the development of a boneless niche model.

Abnormal accumulation of ceramide leads to macrophage-driven inflammation and multiple organ system pathologies, impacting bone, cartilage, the immune system, the central nervous system (CNS), lungs, and other organs. It is a progressive disease with profound morbidity and often premature death. Early recognition of core symptoms of Farber disease is necessary for accurate referral and treatment. This program provides an educational framework to shorten delays in diagnosis, and discusses new approaches that can ultimately impact a patient's long-term outcome.

In this episode, I converse with Dr. Rubul Mout, a Research Fellow at Harvard Medical School and at the Stem Cell Program, Boston Children's Hospital (BCH). Born, brought up, and educated in India, Dr. Mout moved to the United States to pursue his PhD from the University of Massachusetts, Amherst. Prior to joining Harvard/BCH, he was a Washington Research Foundation Innovation Fellow at the Institute for Protein Design, University of Washington. Dr. Mout is the inventor of numerous technologies in gene editing and protein design, and in the last decade he developed a technology for intracellular protein delivery and gene editing in mammalian cells, termed as the ‘E-tag' method, which was in 2020, granted a patent by USPTO (the United States Patent and Trademark Office). At Harvard/BCH, Dr. Mout works to engineer bone marrow stem cells (Hematopoietic stem cells, or HSCs) to cure genetic diseases of blood origin and uses various technologies, including techniques he invented in his prior research, to engineer these HSCs. In particular, he uses patient-derived induced pluripotent stem cells (iPSC) to differentiate them to HSC first, and then to produce and train T-cells that could potentially fight off many diseases. We indulge in a terrific conversation on his magnificent journey through science and life inspired by his innate curiosity; growing up in a poor peasant's family in a far remote corner of Northeast India, near the Assam-Arunachal border; undertaking a majestic quest from Tinsukia to Mumbai to Amherst to Seattle to Boston; inspirational mentors like GK Johori, David Baker, Vincent Rotello, and George Daley; fantastic dedication to scientific outreach and activism; writing outstanding books including a popular bestseller that chronicled his splendid journey; and many more things!!

If you've studied the hematopoietic system malignancies—all the leukemias, lymphomas, and plasma cell disorders—you probably feel like you've been hit with the good old medical school fire hose. Now's a good time to take a step back from all the details, make sure that you remember the underlying framework, and pull together some information that connects several different diseases. In this brick, we'll revisit some of the hematopoietic diseases that we often talk about in pairs: acute vs chronic leukemias, benign lymph node diseases vs lymphoma, and low-grade vs high-grade lymphomas. Also, in case you haven't already done this on your own, we'll pull together all the important translocations, their respective diseases, and the reasons why we should remember them. After listening to this AudioBrick, you should be able to: Compare and contrast acute and chronic leukemias. Compare and contrast the morphologic features of benign follicular hyperplasia and follicular lymphoma. Compare and contrast the morphologic and clinical features of low-grade and high-grade lymphomas and give examples of each. Know the following translocations and name the disease (and prognostic significance, if any) associated with each: t(8;21), t(15;17), inv(16), 11q23, FLT3 mutation, t(9;22), t(11;14), t(14;18), and t(8;14).
