The CD146 (LSEC) antibody also binds to endothelial cells from a various range of organs, such as skin, liver, kidney, brain, spleen, lymph node, intestine, heart and skeletal muscle as well as on blood vessel structures, such as pulmonary arteries, veins, and the capillary network of the alveolar walls but not on lymphatic endothelium. In contrast to humans that express CD146 also on T cells or follicular dendritic cells, murine CD146 expression was only found on a subset of NK1.1
