title: Characterization of Semaphorin 6A-Mediated Effects on Angiogenesis Through Regulation of VEGF Signaling.
abstract: Angiogenesis identifies the process of endothelial cell sprouting and remodeling leading to the formation of new and functional blood vessels. Vascular expansion during development and in the adult mammal provides nutrients and oxygen to areas with increased need. Although many molecules and pathways have been identified as regulators of angiogenesis, aspects of this complex process remain unclear. Particularly undefined are the signals that orchestrate vessel survival and pruning once new blood vessels have sprouted. These poorly characterized aspects of angiogenesis need exploration. This chapter describes the experiments and methods enabling the characterization of Semaphorin 6A as a critical regulator of endothelial cell survival and vessel function.
