Bryan Johnson Says He Created a Newborn Clone to Advance Anti‑Aging Research

Tech entrepreneur and longevity advocate Bryan Johnson, 48, disclosed on X that he has generated a “baby‑Bryan” from his own blood cells. Using induced pluripotent stem‑cell (iPSC) technology, the cells were reprogrammed to an embryonic‑like state and now live in a petri dish. Johnson describes the line as a newborn clone that could serve as his personal blood donor, a platform for testing therapies, and a source for growing transplantable organs and new treatments.

The announcement followed Johnson’s recent revelation that he has been diagnosed with autoimmune gastritis, a condition he says has no cure. He framed the development as a “frontier of new paths” to reverse aging, noting he spends millions annually on his Blueprint protocol and already uses blood transfusions from his teenage son. Medical experts caution that the term “clone” is misleading; the procedure creates reprogrammed stem cells, not a separate human organism, and such work is confined to laboratory research.

Johnson’s claim has drawn both fascination and skepticism, highlighting the gap between experimental stem‑cell techniques and practical anti‑aging therapies.
