The morphogenetic events that occur during angiogenic sprouting involve several members of the Rho family of GTPases, including Cdc42. However, the precise roles of Cdc42 in angiogenic sprouting have been difficult to elucidate owing to the lack of models to study these events in vitro. Here, we aim to identify the roles of Cdc42 in branching morphogenesis in angiogenesis. Using a 3D biomimetic model of angiogenesis in vitro, where endothelial cells were seeded inside a cylindrical channel within collagen gel and sprouted from the channel in response to a defined biochem. gradient of angiogenic factors, we inhibited Cdc42 activity with a small mol. inhibitor ML141 and examined the effects of Cdc42 on the morphogenetic processes of angiogenic sprouting. We find that partial inhibition of Cdc42 had minimal effects on directional migration of endothelial cells, but led to fewer branching events without affecting the length of these branches. We also observed that antagonizing Cdc42 reduced collective migration in favor of single cell migration. Addnl., Cdc42 also regulated the initiation of filopodial extensions in endothelial tip cells. Our findings suggest that Cdc42 can affect multiple morphogenetic processes during angiogenic sprouting and ultimately impact the architecture of the vasculature.
