While on the path to curing her own type 1 diabetes, documentary filmmaker Lisa Hepner was given unprecedented access to a cutting-edge clinical trial involving stem cells. Along with her husband Guy Mossman, they created the new film “The Human Trial,” a movie over ten years in the making that explores the human side of research and the people behind it. She shares what she learned over the course of this journey, how far research still has to go, and whether or not there’s hope for a cure.
