Immunohistochemistry of endothelial cells and αvβ3 integrin. The graphs in a and b show areal percentages of myocardium stained with CD31 antibodies (endothelial cells) and αvβ3 integrin antibodies, respectively. Integrin αvβ3 staining correlates with the [68Ga]NODAGA-RGD uptake measured by autoradiography in the viable ischemic area, in the injured area and in the remote area (c)
