The capacity of the human central nervous system to regenerate after injury or illness is limited, and the resulting functional impairments carry a vast societal and personal burden. In glaucoma, degeneration of retinal ganglion cells (RGCs) - the axons of which form the optic nerve connecting the retina to the brain—leads to permanent blindness; there is currently no effective treatment for RGC degeneration. Now, University of Nebraska Medical Center researcher Iqbal Ahmad and colleagues show that human RGCs can be regenerated in an in vitro setting helped by lessons learned in rodent models. The discovery is detailed in the journal Development.
