Vascular endothelial growth factor A (VEGF-A) is a glycosylated mitogen that specifically acts on endothelial cells and has various other effects including mediating increased vascular permeability, inducing angiogenesis, vasculogenesis and endothelial cell growth, promoting cell migration, and inhibiting apoptosis. Alternatively spliced transcript variants of VEGF-A, encoding either freely secreted or cell-associated isoforms, have been characterized.[1]
As its name implies, VEGF-A activity has been studied mostly on cells of the vascular endothelium, although it does have effects on a number of other cell types (e.g., monocytes/macrophages, neurons, cancer cells, kidney epithelial cells). In vitro, VEGF-A has been shown to stimulate endothelial cell mitogenesis and cell migration. VEGF-A is also a vasodilator and increases microvascular permeability and was originally referred to as vascular permeability factor.
In humans, elevated levels of this protein are linked to POEMS syndrome, also known as Crow-Fukase syndrome.[2] Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy.[3]
