Method to Study the Role of Galectins in Angiogenesis In Vivo Using the Chick Chorioallantoic Membrane Assay

Angiogenesis is a complex multi-step 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. This chapter describes a method to study galectins during physiologic and pathophysiologic angiogenesis in vivo using the chicken chorioallantoic membrane (CAM) assay.
