Join us as Dr. Noah Davidsohn, Co-Founder and Chief Scientific Officer of Rejuvenate Bio, reveals how systemic multi-gene therapy and in vivo partial cellular reprogramming can reverse age-related chronic diseases and double remaining lifespan. Discover the breakthrough science of AAV vector delivery, FGF21 and sTGFβR2 synergy, and companion animal clinical translation.


What if a single gene therapy injection could simultaneously treat heart failure, kidney disease, and diabetes? In this episode, we sit down with Dr. Noah Davidsohn, CSO and Co-Founder of Rejuvenate Bio, spun out of George Church’s lab at Harvard Medical School. Dr. Davidsohn breaks down their landmark 2024 study in Cellular Reprogramming, which demonstrated a 109% increase in the remaining lifespan of extremely aged (124-week-old) wild-type mice using systemic AAV9 delivery of Yamanaka factors (OSK). He explains the mechanics of intermittent doxycycline pulsing to avoid tumor risks, the power of multi-gene master regulators like FGF21 and sTGFβR2 in RJB-01, and how treating companion dogs with Mitral Valve Disease serves as the ultimate translational bridge to human clinical trials.
