Dll4 (Delta-like 4), a membrane-bound Notch ligand, plays a fundamental role in vascular development and angiogenesis. It is highly expressed in capillary endothelial tip cells and is involved in suppressing neighboring stalk cells to become tip cells during angiogenesis. Dll4-Notch signaling is mediated either by direct cell-cell contact or by Dll4-containing exosomes from a distance. DLL4 signaling is extensively critical for tumor angiogenesis. Blockage of DLL4 signaling inhibits tumor growth by deregulating angiogenesis and promoting non productive angiogenesis. Additionally, DLL4 has been shown to help regulate the cellular actions of VEGF.
