Myocardial vasculature is LMO2−. A, Adult myocardial vasculature is LMO2− (×400). B, The rich microvasculature is evident on CD31 immunostain (×400). C, Similarly, fetal myocardial vasculature is LMO2− (×400). D, CD31 highlights the vasculature (×400). E and F, By contrast, adult skeletal muscle vasculature (E, ×400) and fetal skeletal muscle vasculature (F, ×400) are LMO2+.
