Abstract
GTPases control a myriad of cellular processes, including cell migration, proliferation, polarity, and cell adhesion, which includes cell-cell junction regulation. Angiogenesis requires many of these diverse cellular events to occur appropriately. In this chapter, we describe the techniques for in vitro assessment of GTPase activity in endothelial cells grown in monolayer culture as a model system for studying their role during angiogenesis.
