In July 2026, Daylon and Arun attended the International Society for Stem Cell Research’s (ISSCR) annual meeting in Montreal, and recorded daily episodes discussing highlights of the previous 24 hours. Here is the second of four episodes, where Daylon and Arun discuss promising stem cell clinical trial updates for Parkinson's disease, advances in cardiac, thymus, and vascular organoid research, and new technologies that are reshaping developmental biology and regenerative medicine. They also reflect on inspiring patient stories, tributes to stem cell pioneer Sir John Gurdon, and the growing role of AI and engineering in the future of stem cell research.
