Abstract In the adult, angiogenesis, the formation of new blood vessels from pre-existing vasculature contributes to the pathogenesis of many disorders including cancer. The role of adhesion molecules, especially integrins, in pathological angiogenesis has long been the subject of investigation, mostly because of their potential as anti-angiogenic targets. Recent studies have highlighted the complexities connected with understanding the roles of one particular integrin, alphavbeta3, in neovascularization. This integrin is notoriously promiscuous and its precise functions in angiogenesis are unclear. Here, I have firstly summarized some of the salient features of the roles played by alphavbeta3 during angiogenesis; secondly attempted to address the apparently conflicting issues surrounding this topic; and finally raised some questions that appear to be unanswered.
