What if we could reverse degenerative forms of blindness with but an injection of new cells? Stem cell therapies—still promising, if not particularly speedy—may someday do just that. A recent paper in the journal Nature Biotechnology documents the successful implantation of photoreceptor cells, grown from embryonic stem cells, into the retinas of night-blind mice. The cells not only took root, but they remained present six weeks after implantation and formed the necessary neural connections to communicate visual data to the brain.
In 2009, 12 people participated in a clinical trial through which they received an experimental gene therapy for an inherited form of blindness. The correct… read more
