In July 2024, Daylon and Arun attended the International Society for Stem Cell Research’s (ISSCR) annual meeting in Hamburg, Germany, and recorded daily episodes discussing highlights of the previous 24 hours. Here is the second of four episodes from the meeting. Highlights from Day 2 include Dr. Helmuth Gehart’s work on mesothelioma organoids, Dr. Kyoko Miura’s research on aging in naked mole rats, and Dr. Mansi Srivastava’s talk on panther worms to study pluripotency during development.
