https://www.nytimes.com/2026/04/27/magazine/cell-rejuventation-biotech-longevity-research-altos-labs.html. This is a recent article in the New York Times on a new treatment for age related disease using cell rejuvination. So far most of the successes were on lab mice and rats. For example they removed a failing kidney from a lab rat, rejuvinated it , and reattached it. So far these tests are on lab animals, but they are starting a study on humans for an age related disease: glaucoma. If this experimental treatment is successfull I expect age related diseases of the retina will soon follow.
