Summary:
British scientists have discovered non-dividing retinal cells implanted into adult mouse retina can generate new photoreceptors. The results, say the researchers, suggest precursor cells grown from human adult or embryonic stem cells might also serve to restore sight, and challenge the assumption that stem cells offer the best prospect for tissue repair.
Commentary: Maybe this finding will eventually lead to stem cell treatments for eye diseases and disorders in humans that avoid the ethical controversy that has been associated with embryonic stem cells.
