Integrating the VEGF signals leading to actin-based motility in vascular endothelial cells

Vascular endothelial growth factor (VEGF) is a potent pro-angiogenic factor that stimulates endothelial cell proliferation and migration, two key events of the angiogenic process. The intracellular signals leading to these events have recently been investigated and a better understanding on how VEGF induces its angiogenic functions is emerging. Herein, we summarize recent findings on how VEGF stimulates endothelial cell migration and contributes to angiogenesis. In particular, the role of the VEGF receptors involved in initiating the coordinated signals that leads to actin-based motility is discussed.
