ANGPTL4 is expressed in hemangioma of infancy. Representative images of immunohistochemistry. The panels represent (a) no antibody control, (b) human infant foreskin sample stained with ANGPTL4, and (c) infantile hemangioma sample stained with Angptl4. The scale bars represent 100 μm (a, c) and 50 μm (b). Infantile hemangioma samples highly express ANGPTL4 proteins in endothelial cells, while human foreskin sample consists of largely negative cells surrounded by artifactually stained tissue
