Bevacizumab link to the VEGF and inhibits the interaction of VEGF to its receptors (Flt-1 and KDR) on the surface of endothelial cells. The combination of VEGF with its receptors causesendothelial cell replication and new blood vessel formation in in vitro models of angiogenesis. Administration of bevacizumab to xenotransplant models of colon cancer in nude (athymic) mice caused reduction of microvascular growth and inhibition of metastatic disease progression.
