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 third of four episodes from the meeting. Highlights from Day 3 include Dr. Yasuhiro Takashima's work on bilaminoids, Dr. Clive Svendsen's talk on organoid models for ALS, Dr. Sharon Gerecht's research on modeling the microenvironment, and Dr. Katsuhiko Hayashi's work with gonadal organoids.
