From: Integrin αvβ3 Expression in Colon Carcinoma Correlates with Survival
Detection of αvβ3 integrin expression on frozen sections of colon carcinoma and normal colon tissue. αvβ3 integrin was detected on endothelial cells of the tumor vasculature (arrow). In larger vessels, we observed, in addition, labeling within the vessel wall indicating expression of αvβ3 integrin by smooth muscle cells. Control sections were not incubated with the primary antibody but were included in all following staining steps (bar = 50 μm).
