Retinal pigment epithelium

Color-enhanced image taken by a scanning electron microscope of retinal pigment epithelial (RPE) cells derived from human embryonic stem cells. The cells are remarkably similar to normal RPE cells, having a hexagonal shape and growing in a single, well defined layer. These cells are the ones responsible for macular degeneration, the most common cause of blindness. CIRM scientists hope to one day treat macular degeneration with transplanted RPE cells derived from human embryonic stem cells.


The image was taken in the lab of David Hinton at the University of Southern California.
