#473: Why Most "Regenerative" Therapies Fail | Revolutionary Immune Hacks and Stem Cell Breakthroughs With Dr. Rafael Gonzalez

📍 Good news! My original Instagram is back! Please follow my original account at https://www.instagram.com/nathalieniddam/ and also my backup account at https://www.instagram.com/longevitywithnat/. Today, I’m joined by Dr. Rafael Gonzalez, a longtime leader in regenerative medicine whose work spans everything from spinal cord injuries to cutting-edge immune modulation and stem cell therapies. Dr. Gonzalez takes us through his journey from studying secondary degeneration in the nervous system to diving deep into what actually drives healthy aging—and what most people get wrong about immune decline, senescent cells, and the promise (and pitfalls) of regenerative interventions.
