Scientists Have Restored Eyesight in Mice in 'Milestone' Anti-Ageing Treatment

Scientists said Wednesday they have restored sight in mice using a “milestone” treatment that returns cells to a more youthful state and could one day help treat glaucoma and other age-related diseases. The process offers the tantalising possibility of effectively turning back time at the cellular level, helping cells recover the ability to heal damage caused by injury, disease and age. To turn back the clock, they modified a process usually used to create the “blank slate” cells known as induced pluripotent stem cells. “The effects of OSK in people remain to be tested but the existing results suggest that OSK is likely to reprogramme brain neurons across species,” he wrote in a review commissioned by Nature.
