General description
MUC18 antigen (CD146), a member of the immuoglobulin superfamily, is an intrinsic membrane glycoprotein of 110-120 kDa found on the surface of endothelial cells, bone marrow fibroblasts and various melanomas. MUC18 has been used as a marker of tumor progression in human melanoma because expression in those tumors correlates strongly with poor prognosis and the development of metastic disease. In addition, a number of human T, B and myeloid leukemic cell lines seem to express MUC18. The close structural relationship with N-CAM and related molecules suggests that MUC18 may be also a developmentally regulated cell adhesion molecule (Melanoma adhesion molecule or MCAM).
Specificity
Detects circulating endothelial cells in human. Expected to cross-react with dog & mouse.
P1H12 reacts specifically with CD146 {MCAM, MUC18}. In blood and marrow P1H12 reacts only with endothelial cells, and has been used to detect circulating endothelial cells in human, dogs and mouse samples. It positively stains normal, primary HUVEC and MVEC cultures and the endothelial cells of all vessels in normal frozen sections of human skin, intestine, ovary tonsil, lymph node, lung, and kidney. It does not stain carcinoma cell lines HT-29 and COLO205, and M21, the T cell lines Jurkat and HuT78, fibroblasts, HL-60 or CHO cells, or EBV-transformed B cell lines, although it expected that CD146 expression is present in many tumor lines. P1H12 does not stain normal monocytes, granulocytes, red cells, platelets, T cells or B cells from marrow or peripheral blood; nor does it detect marrow megakaryocytes or the megakaryoblast line HU3. The peripheral blood cells that do stain with P1H12 also are positive for both von Willebrand Factor (vWF) and thrombomodulin (the combined expression of which is limited to endothelium), and they stain for flt and flk. In recent testing, melanoma A2058, SKMEL.3 and A375.S2 are positive, while murine melanoma M3 is negative. One smooth muscle line (HISM) was positive and one negative (TIGHA-VSMC). Human blood lymphoctes are negative with or without prior stimulation.

To gain a molecular understanding of tumor angiogenesis, we compared gene expression patterns of endothelial cells derived from blood vessels of normal and malignant colorectal tissues. Of over 170 transcripts predominantly expressed in the endothelium, 79 were differentially expressed, including
