Stabilization of the retinal vascular network by reciprocal feedback between blood vessels and astrocytes [PDF]

, 2005
Development of the retinal vasculature is controlled by a hierarchy of interactions among retinal neurons, astrocytes and blood vessels. Retinal neurons release platelet-derived growth factor (PDGFA) to stimulate proliferation of astrocytes, which in ...
