Dr. Thorsten Boroviak is an Assistant Professor at the University of Cambridge and a member of the Cambridge Stem Cell Institute. He discusses how stem cell–based embryo models are helping researchers study early human and primate development, including implantation and gastrulation. He also talks about using primate systems such as marmoset to understand human development, the role of biomechanics and extraembryonic tissues in embryogenesis, and the ethical considerations surrounding embryo models and emerging technologies like in vitro gametogenesis.

Mitophagy Controls Blood Stem Cells – Embryonic blood stem cells expand while staying multipotent thanks to tightly controlled ROS levels regulated by developmental mitophagy.

SLC4A3 Variants Drive Arrhythmia Risk – Mutations in SLC4A3 raise intracellular pH in heart cells, which shortens electrical signals and increases the risk of dangerous arrhythmias.

HSC Dynamics After Myeloablation – After chemotherapy, blood stem cells briefly boost differentiation to rebuild the blood system before returning to normal.

Modeling Duchenne Cardiomyopathy – Scientists generated heart organoids from Duchenne muscular dystrophy patient stem cells that mimic cardiomyopathy.

Drs. Shuibing Chen and Hans Clevers, members of the Steering Committee for the ISSCR Consortium on Advanced Stem Cell-Based Models in Drug Discovery and Development, discuss the need to accelerate the responsible integration of stem cell–derived models into preclinical drug development. Their conversation reflects growing regulatory and policy momentum around new approach methodologies (NAMs) and underscores the importance of rigorous standards, regulatory alignment, and cross-sector collaboration to improve reproducibility and advance more predictive, human-relevant therapies.

Building on its long-standing leadership in global standards, ethics, and policy, the ISSCR is uniquely positioned to convene industry, academia, and regulators around this effort. The initiative also reflects the Society’s expanding industry engagement, with industry membership increasing nearly 180% over the past five years – creating new opportunities for strategic partnerships to address shared scientific and translational challenges.

Treating Frailty with Stem Cells – In a clinical trial, mesenchymal stem cell therapy improved walking distance and physical function in older adults with frailty.

Combined Bone & Bone Marrow Organoids – Researchers developed a scalable iPSC-derived bone marrow organoid that models human lympho-myeloid hematopoiesis and disease.

CAR-NK Progenitors Prevent Relapse – Engineered pluripotent stem cell–derived CAR-expressing NK progenitor cells reduced minimal residual disease and prevented relapse in leukemia models following chemotherapy.

Whole-Body Single-Cell Mapping – Scientists have developed a 3D single-cell-resolution map of mouse organs and the whole neonatal body.

Drs. Fiona Doetsch and Nozomu Yachie, Co-Chairs of the ISSCR 2026 Annual Meeting Program Committee, join the podcast to discuss what to expect at the upcoming ISSCR 2026 meeting taking place in Montreal, Canada from July 8 – 11, 2026. This is the world’s largest and most comprehensive gathering dedicated to stem cell research and regenerative medicine, bringing together global leaders across basic science, technology development, translational research, and clinical application. They discuss the meeting’s global focus, program highlights, and spotlight the many new invited speakers and expanded opportunities for trainees to present and network.

HCMV Infection and Cholangiocyte Barriers – Scientists show that human cytomegalovirus infection induces epithelial–mesenchymal transition in cholangiocytes.

Cross-Circulation for Liver Failure – Extracorporeal cross-circulation with genetically modified pig livers provided effective temporary liver support with minimal immune response in a human decedent model.

How Sleep Loss Hurts the Gut – Researchers identified a sleep deprivation-responsive neural circuit that controls intestinal stem cell function.

Mapping the Fetal Stem Cell Niche – Scientists demonstrate a central role of hepatoblasts in the regulation of fetal liver hematopoiesis and stem cell maintenance.
