CD31/PECAM1 is commonly used as an endothelial marker, particularly in angiogenesis. CD31/PECAM1 is important in assisting placental and endometrial vascular development. However, CD31/PECAM1 is also associated with many negative angiogenic occurrences, particularly those within or related to tumors and other disease lesions. In MS, plasma microparticules carry CD31/PECAM1 and are important in the formation of brain lesions associated with MS. In cardiac angiosarcoma, CD31/PECAM1 presence is indicative of the severity of the disease. In prostate tumor cells, CD31/PECAM1 is upregulated and associated with increased levels of HIF1a, VEGF, and other hypoxic markers. This relationship seems to indicate that when prostate cancer reaches a sufficient state of development that intense angiogenesis must occur in order to support the ongoing growth and survival of the cancer cells. In all, CD31/PECAM1 is a great marker for normal and disease-induced angiogenesis.
