Unlike ECs, VM-lining tumor cells express NRP1, VEGF-C, TIE-1, endoglin, tissue factor pathway inhibitor (TFPI1), laminin subunit γ2 (LAMC2), and EphA2, whereas they do not express VEGF receptors -1 and -2, TIE-2, CD31, vascular adhesion protein-1 (VCAM-1) and P-selectin [322]. This evidence concerns the gene NRP1 and neoplasm.
