Examination of the role of galectins during in vivo angiogenesis using the chick chorioallantoic membrane assay.

Angiogenesis is a complex multi-process involving various activities of endothelial cells. These activities are influenced in vivo by environmental conditions like interactions with other cell types and the microenvironment. Galectins play a role in several of these interactions and are therefore required for proper execution of in vivo angiogenesis. In this chapter we describe a method to study galectins and galectin inhibitors during physiologic and pathophysiologic angiogenesis in vivo using the chicken chorioallantoic membrane (CAM) assay.
