In June 2025, Daylon and Arun attended the International Society for Stem Cell Research’s (ISSCR) annual meeting in Hong Kong, and recorded daily episodes discussing highlights of the previous 24 hours. Here is the first of four episodes, where Daylon and Arun discuss updates from clinical trials for ALS, congenital heart disease, and Parkinson’s disease. They also talk about the Presidential Plenary session, chaired by Dr. Valentina Greco.
