The three blind mice will be able to see where they're running soon enough!
Thanks to an experimental study using specialized stem cells. Researchers from the University College London implanted the stem cells into mice that had lost their vision because of diseases like macular degeneration. Actually, this didn't work in earlier studies where the stem cells implanted were very young and not programmed to become certain cells yet.
But this time, the stem cells used were already programmed to become light-sensing cells before they were implanted in the blind mice and this time, the mice that were blind could actually see again.
It's promising news in the lab, but researchers admit it will be a while before this can even be tried in humans.
