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 ...

Astrocyte-derived vascular endothelial growth factor stabilizes vessels in the developing retinal vasculature [PDF]

, 2010
Vascular endothelial growth factor (VEGF) plays a critical role in normal development as well as retinal vasculature disease. During retinal vascularization, VEGF is most strongly expressed by not yet vascularized retinal astrocytes, but also by retinal ...
