My guest is Dr. Sergiu Pașca, MD, professor of psychiatry and behavioral sciences at Stanford University. We discuss the biology and genetics of autism, why autism diagnoses are increasing and recent progress in using stem cells to understand and treat profound autism and other brain disorders. Dr. Pașca explains “organoids and assembloids”—human stem cell–derived tools he pioneered to study, treat and cure complex brain diseases. We also discuss ethical and safety issues with using gene editing and stem cells in humans.
