Ep. 284: “Organ Chip Engineering” Featuring Dr. Milica Radisic Dec 10, 2024

Show notes

Dr. Milica Radisic is a Professor and Canada Research Chair at the University of Toronto. Her lab uses organ-on-a-chip engineering to mimic physiology of the heart, kidney, and vasculature for the purpose of modeling human disease and discovering more effective drugs. In this episode, she talks about the challenges of studying the heart and strategies to mature cardiomyocytes. She also discusses using macrophages to vascularize heart-on-a-chip platforms and enhance cardiac tissue function, sustainability considerations for microfluidic chips, and how these disease models can reduce the use of lab animals. Finally, she talks about starting a company to commercialize her lab's cardiac chip platform, the landscape for women entrepreneurs, and advice from her mentor, Dr. Bob Langer.

Ep. 283: “Molecular Hematopoiesis” Featuring Dr. Cynthia Dunbar Dec 03, 2024

Show notes

Dr. Cynthia "Cindy" Dunbar is National Institutes of Health (NIH) Distinguished Investigator and Chief of the Translational Stem Cell Biology Branch at the National Heart, Lung, and Blood Institute of the NIH. She talks about using macaques to study hematopoiesis and aging, and the challenges and considerations for using these models. She also discusses her collaborative study transplanting iPSC-derived cardiomyocytes into rhesus macaques, as well as the NIH's unique research environment and her musical talents outside of the lab.

Ep. 282: “Whole-Body Regeneration” Featuring Dr. Mansi Srivastava Nov 26, 2024

Show notes

Dr. Mansi Srivastava is Professor of Organismic and Evolutionary Biology at Harvard University and Curator of Invertebrate Zoology at the Harvard Museum of Comparative Zoology. Her lab uses distantly related species to study evolution and regeneration. She talks about establishing Hofstenia miamia, or the three-banded panther worm, as a model system. She also discusses her lab's work on adult stem cell lineage tracing and whole-body regeneration in Hofstenia, as well as her scientific outreach efforts.

Ep. 281: “Fertility Treatments” Featuring Drs. Dina Radenkovic and Bruna Paulsen Nov 12, 2024

Show notes

Drs. Dina Radenkovic and Bruna Paulsen are Co-Founder & CEO and VP of Manufacturing and Therapeutic development at Gameto, a biotech company developing treatment solutions to improve women's reproductive health. Their lead platform, Fertilo, uses ovarian support cells to mature oocytes outside of the body with the goal of making IVF and egg freezing shorter, safer, and more effective.
