Vascular endothelial growth factor (VEGF, / v ɛ dʒ ˈ ɛ f /), originally known as vascular permeability factor (VPF), [1] is a signal protein produced by many cells that stimulates the formation of blood vessels. To be specific, VEGF is a sub-family of growth factors, the platelet-derived growth factor family of cystine-knot growth factors.
Vascular endothelial growth factor A (VEGF-A) is a dimeric glycoprotein that plays a significant role in neurons and is considered to be the main, dominant inducer of the growth of blood vessels. VEGFA is essential for adults during organ remodeling and diseases that involve blood vessels, for example, in wound healing, tumor angiogenesis ...
The hypoxia that is noted in these areas causes the tissues to demand the presence of nutrients and oxygen that will allow the tissue to carry out metabolic activities. Because of this, parenchymal cells will secrete vascular endothelial growth factor which is a proangiogenic growth factor. [11]
Vascular endothelial growth factor C (VEGF-C) is a protein that is a member of the platelet-derived growth factor / vascular endothelial growth factor (PDGF/VEGF) family. It is encoded in humans by the VEGFC gene , which is located on chromosome 4q34.
Growth factors that inhibit neovascularization include those that affect endothelial cell division and differentiation. These growth factors often act in a paracrine or autocrine fashion; they include fibroblast growth factor, placental growth factor, insulin-like growth factor, hepatocyte growth factor, and platelet-derived endothelial growth ...
These tumor-associated endothelial cells can also release factors and supply nutrients that promote the growth of the primary tumor mass and its aggressive spread. [2] [31] Additionally, angiogenesis is intimately linked to metastasis, as delivery of nutrients and oxygen through blood vessels is required for invasive tumor growth and spread. [32]

FLT1 is a member of VEGF receptor gene family. It encodes a receptor tyrosine kinase which is activated by VEGF-A, VEGF-B, and placental growth factor.The sequence structure of the FLT1 gene resembles that of the FMS (now CSF1R) gene; hence, Yoshida et al. (1987) proposed the name FLT as an acronym for FMS-like tyrosine kinase.
