Specificity:ab78451 reacts specifically with CD146. In blood and marrow ab78451 reacts only with endothelial cells, and has been used to detect circulating endothelial cells in human, dogs, rabbits and mouse samples. ab78451 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, EBV-transformed B cell lines, 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 ab78451 are also 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. We have data to indicate that this antibody may not cross react with Rat. However, this has not been conclusively tested and expression levels may vary in certain cell lines/tissues.

CD146 also known as MCAM or MUC18 is a cell adhesion molecule that belongs to the immunoglobulin superfamily. With a mass of approximately 113 kDa CD146 is expressed mainly on the surface of endothelial cells but it can also be found on smooth muscle cells some T-cells and in certain cancerous tissues. This protein plays a role in cell-cell adhesion contributing to the integrity and signaling functions within tissue microenvironments.
Biological function summary
CD146 influences the migration and organization of cells within the vascular system. It serves as a component of cell adhesion complexes facilitating interactions between endothelial cells and other cell types. Additionally CD146 contributes to angiogenesis the process by which new blood vessels form from existing vasculature which is critical during tissue development and repair. This function makes it an important element in maintaining normal physiological processes.
Pathways
CD146 participates in the Wnt/β-catenin and MAPK signaling pathways which are vital in cell proliferation and differentiation. Through the Wnt/β-catenin pathway CD146 interacts with other proteins like Frizzled receptors to regulate gene transcription. In the MAPK pathway it is linked with signaling cascades that involve proteins such as ERK leading to cellular responses necessary for growth and response to external stimuli.
CD146 has been implicated in melanoma progression and cardiovascular diseases. Its overexpression in melanoma associates it with increased tumor growth and metastasis often involving interactions with other adhesion molecules like integrins. In cardiovascular diseases CD146 relates to atherosclerosis as its expression on endothelial cells can promote inflammatory responses. Understanding these connections provides insights into potential therapeutic targets for treating these conditions.
