Cell Transplants for Macular Degeneration

This item is from Gail Johnson:

A stem-cell startup aims to test neural stem cells for treating two leading causes of blindness.

Reviving the retina: Human neural stem cells injected into the retina of rats that were engineered to go blind form a layer of tissue (purple) between the animals’ photoreceptors (blue) and retinal pigment epithelium (black), which typically nourishes photoreceptors. A startup called StemCells aims to begin human testing of the cells for retinitis pigmentosa and macular degeneration, two degenerative diseases that cause blindness.
