Stem cell study offers hope for hereditary blindness condition

Posted: 28/09/2010 |

Bio News is reporting that researchers have successfully transplanted retinal cone cells into blind mice, making progress towards a stem cell treatment for a form of blindness that causes degeneration of the eye's retina. The research team, from the University College London Institute of Child Health, isolated immature photoreceptors – light-sensitive cells – from the developing retina. They transplanted these cells into the eyes of adult mice with Leber's congenital amaurosis, a form of degenerative blindness. The transplanted cells integrated into the retina and became mature 'cone' photoreceptors, the cells required for colour vision.
