Clinical Significance:

Thrombomodulin (CD141) is a transmembrane glycoprotein of 75 kD which can accelerate the activation of protein C. Activated protein C functions as an anticoagulant by combining with protein S to inactivate factors Va and VIIIa of the blood coagulation pathway and by binding thrombin. Thrombomodulin has been identified within a number of normal tissues. These include the lining cells of arteries, veins, capillaries and the lymphatics as well as mesothelial cells, meningeal lining cells, synovial cells, syncytiotrophoblasts, megakaryocytes and platelets. It may be demonstrated immunohistochemically in mesothelial cells, some squamous cell carcinomas, trophoblastic tumors, urothelial carcinomas, vascular tumors, and some synovial sarcomas.
