The gene editing tool CRISPR along with stem cells help scientists create retinal ganglion cells in the lab
Degeneration of retinal ganglion cells often leads to progressive and irreversible vision loss. These cells are the type of nerve cells located within the retina, which transmit visual signals from the eye to the brain. Retinal ganglion cells have limited intrinsic capacity to regenerate and cannot be replaced by new cells. Glaucoma and multiple sclerosis are the most common type of optic neuropathies that lead to vision loss and blindness due to death of retinal ganglion cells.
