Surface of a mouse retina. It looks like a delicate floral structure. In fact it is the surface of a mouse retina. Produced by combining more than 400 images captured through a technique known as confocal microscopy, this digital reconstruction shows the retina’s blood vessels in blue while the red and green highlight cells known as astrocytes. These star-shaped cells are involved in myriad crucial processes that support and maintain neurons. Scientists hope that by understanding what astrocytes are up to as the retina deteriorates, they might find new ways to treat vision loss.
