Exosomes surrounding retinal ganglion cells
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 study was conducted by researchers at the National Eye Institute (NEI), part of the National Institutes of Health.
This microscopy image shows exosomes (green) surrounding retinal ganglion cells (orange and yellow).
