Background
VEGF164, a growth factor with pivotal roles in angiogenesis, vasculogenesis, and endothelial cell growth, orchestrates a range of cellular responses crucial for vascular development. It stimulates endothelial cell proliferation, facilitates cell migration, prevents apoptosis, and enhances blood vessel permeability by binding to receptors such as FLT1/VEGFR1 and KDR/VEGFR2, as well as heparan sulfate and heparin. During lactation, VEGF164 may contribute to increased vascular permeability, supporting efficient transport of molecules for milk protein synthesis. Additionally, its interaction with the NRP1 receptor initiates signaling pathways essential for motor neuron axon guidance and cell migration, underscoring its involvement in embryonic development processes. Existing as a homodimer with disulfide linkage, VEGF164 also forms a heterodimer with PGF and interacts with isoform 2 of BSG, revealing its multifaceted molecular interactions.
Verified Bioactivity
Measured in a cell proliferation assay using human umbilical vein endothelial cells (HUVEC) and the ED50 is typically 1-10 ng/mL.
