A newly discovered method of replacing degraded retinal cells with corneal cells could help to prevent, or even cure, blindness.
It was discovered that corneal limbal stromal cells have stem cell properties, which could allow them to be cultured to create retinal cells. Because the corneal cells are on a thick region on the front surface of the eye, they are relatively easy to remove, and since the cells come from the patient's own body, there is less chance of rejection.
