During vertebrate angiogenesis, Notch regulates the cell-fate decision between vascular tip cells versus stalk cells. Canonical Notch signaling depends on sequential proteolytic events, whereby interaction of Notch with membrane-anchored ligands triggers proteolytic processing, first by Adam10 and then presenilins. This liberates the Notch intracellular domain, allowing it to enter the nucleus and activate Notch-dependent genes. Here we report that conditional inactivation of Adam10 in endothelial cells (A10?EC) recapitulates the increased branching and density of the retinal vasculature that is also caused by interfering with Notch signaling. Moreover, A10?EC mice have additional vascular abnormalities, including aberrant subcapsular hepatic veins, enlarged glomeruli, intestinal polyps containing endothelial cell masses, abnormal endochondral ossification, leading to stunted long bone growth and increased pathologic neovascularization following oxygen-induced retinopathy. Our findings support a model in which Adam10 is a crucial regulator of endothelial cell-fate decisions, most likely because of its essential role in canonical Notch signaling.
