Dr. Juan Melero-Martin is an Associate Professor and the Endowed Chair in Cardiac Surgery at Boston Children's Hospital. His lab uses bioengineering principles to understand how vascular networks are formed and the mechanisms by which the vasculature modulates the engraftment and activity of various human stem cells.

Guest: Dr. Carole LaBonne is the Erastus Otis Haven Professor of Molecular Biosciences at Northwestern University. Her lab studies the genesis of neural crest stem cells at the level of the signaling pathways and transcription factors that comprise the neural crest gene regulatory network. They also study how these mechanisms contribute to exit from pluripotency and the subsequent lineage restriction of neural crest cells to their derivative cell types that collectively define vertebrates.

The Stem Cell Science Round Up Creating Modified Cows and Sheep from Haploid Stem Cells – Scientists have successfully derived haploid androgenetic ESCs from cattle and sheep and developed a novel method to generate offspring from these cells. (4:33) Embryonic Stem Cells from Birds – Researchers have succeeded in deriving and maintaining authentic ESCs from chickens and seven other bird species. (13:48) Mutation Hotspots Reveal Spermatogonia Clonal Growth – As men age, harmful genetic mutations in sperm not only accumulate but are also favored during sperm production, giving them a reproductive advantage. (20:35) Canine iPSC Technology – Researchers have established culture conditions for canine iPSCs. (31:10) Photo Reference: Courtesy of Dr. Carole LaBonne Subscribe to our newsletter!

Dr. Lars Velten is a Group Leader at the Centre for Genomic Regulation in Barcelona. He talks about his research on cell-state-specific enhancers in hematopoiesis and lineage tracing techniques to study blood aging. He also discusses combining generative AI with wet lab techniques and the advantages of risk-taking in basic research.

Dr. Alice Soragni is an Associate Professor at the University of California, Los Angeles. She talks about her work on patient-derived organoids and how they can be adapted for drug screening. She also discusses how she transitioned from structural biology to research on protein aggregation and rare diseases, and the current social media landscape for scientists.

Dr. Zhongwei Li is an Associate Professor at the University of Southern California. His lab focuses on kidney organogenesis with translational applications of kidney regeneration and disease modeling. He talks about his work on PSC-derived nephron progenitors and drug discovery applications for polycystic kidney disease.

Dr. Mark Hatley is an Associate Faculty Member and Director of the Division of Molecular Oncology at St. Jude Children's Research Hospital. His research focuses on the developmental origins and genetic mechanisms of pediatric rhabdomyosarcoma. He talks about his work on pediatric oncology and the mechanisms that differentiate normal development from cancer. He also discusses the role of PAX3-FOXO1 and DICER1 in tumorigenesis.

Dr. Jeanne Loring is a Co-Founder of Aspen Neuroscience and Professor Emeritus at Scripps Research. She talks about generating gametes from the functionally extinct northern white rhinoceros, Aspen's early days and its recent clinical trial results for Parkinson's cell therapy, and sending her own stem cells into space. She also discusses the need for genetic variation in iPSC lines.

Dr. James Briscoe is a Group Leader at the Francis Crick Institute and Editor-In-Chief of Development. His lab uses an interdisciplinary approach, including mice, chicks, and other models, to study developmental dynamics. He discusses his lab's work on human trunk formation and his role as an Editor-In-Chief.

In June 2025, we attended ISSCR 2025, the annual meeting of the International Society for Stem Cell Research, in Hong Kong. We spoke with delegates about their research, their impressions of the meeting, and the most memorable research presented. They also discussed their experiences exploring Hong Kong.
