Vascular Endothelial Growth Factor 189 (VEGF189)

Vascular Endothelial Growth Factor 189 (VEGF189)
VEGF189 is almost entirely bound to the cell surface or extracellular matrix, and is considered active after its cleavage and release from its extracellular binding site.VEGF189 induces endothelial cell proliferation and migration in vitro. The 30-60% increase observed with VEGF189 (10 ng/ml) in HUVEC proliferation was similar to that observed with VEGF165. However, the proliferative effect observed with VEGF189 appeared dependent on the origin of the endothelial cell, since the proliferation was clearly observed with HUVEC but not with BAEC or capillary endothelial cells from dermis (HMEC). The effect of VEGF189 on endothelial cell migration was also analyzed using the wound healing and the Boyden chamber assays. The migration effect was observed with BAEC which do not proliferate with VEGF189, suggesting that different mechanisms are involved in proliferation and migration.
