umls-concept:C0078058 | skos:definition | NCI: A substance made by cells that stimulates new blood vessel formation.,NCI: Vascular Endothelial Growth Factor A (232 aa, ~27 kDa) is encoded by the human VEGFA gene. This protein plays a role in both cell proliferation, and angiogenesis.,MSH: The original member of the family of endothelial cell growth factors referred to as VASCULAR ENDOTHELIAL GROWTH FACTORS. Vascular endothelial growth factor-A was originally isolated from tumor cells and referred to as "tumor angiogenesis factor" and "vascular permeability factor". Although expressed at high levels in certain tumor-derived cells it is produced by a wide variety of cell types. In addition to stimulating vascular growth and vascular permeability it may play a role in stimulating VASODILATION via NITRIC OXIDE-dependent pathways. Alternative splicing of the mRNA for vascular endothelial growth factor A results in several isoforms of the protein being produced. | lld:umls |
