Bill Ackman Reveals Daughter Received Experimental Treatment Moving Mitochondria From Her Leg to Her Eyes

Bill Ackman said on X that his 26-year-old daughter, Lucy, was the single patient who received an experimental mitochondrial treatment after a massive brain hemorrhage left her blind. According to a report in Nature, after emergency FDA authorization, doctors at Mount Sinai extracted mitochondria from Lucy’s leg muscle and injected them into the fluid in both eyes. The procedure led her pupils to respond again to light and she reported seeing shapes and shadows with her left eye, but the improvement faded after about four weeks and did not restore normal vision. Ackman said there was no inflammation or rejection, and the study preprint dated Aug. 10 has not been peer reviewed.
