Stem cell secretions may protect against glaucoma

NEI scientists find that stem cell exosomes promote survival of retinal ganglion cells in rats.

A new study in rats shows that stem cell secretions, called exosomes, appear to protect cells in the retina, the light-sensitive tissue in the back of the eye. The findings, published in Stem Cells Translational Medicine, point to potential therapies for glaucoma, a leading cause of blindness in the United States. The study was conducted by researchers at the National Eye Institute (NEI), part of the National Institutes of Health.

Microscopy shows exosomes (green) surrounding retinal ganglion cells (orange and yellow).
