Detailed explanation-1: -Holoclar® is currently the only clinically approved stem cell treatment for the eye. This treatment restores vision to patients with damaged corneas (the clear outermost part of the eye) by transplanting lab-grown limbal stem cells into areas of the eye lacking these cells.
Detailed explanation-2: -A surgical team at the National Institutes of Health (NIH) successfully implanted a patch of tissue made from autologous induced pluripotent stem cells (iPSC) to treat advanced “dry” age-related macular degeneration, the agency announced last week.
