When  scientists transplanted stem-cell-derived photoreceptors into night-blind mice, a small number of the cells integrated into the retina at the back of the eye, they reported in Nature Biotechnology this week.

Stem cells grown “in a dish” can integrate into the back of the eye in night-blind mice, according to a new study from University College London. Prof(...)
