CD105 Information for Pathologists


Also called endoglin. CD105 is a regulatory component of the TGF-beta receptor complex. Mutations in CD105 cause Hereditary Hemorrhagic Telangiectasia type I (Am J Hum Genet 1997;61:68). It is required for hemangioblast and early hematopoietic development (Development 2007;134:3041)

Common Uses By Pathologists:

Specific and sensitive marker for tumor angiogenesis (better than CD31). Increased microvessel staining is also a prognostic factor for Acute lymphoblastic leukemia in children (Leuk Res 2007;31:1741)
Breast carcinoma (Am J Clin Pathol 2003;119:374, including node negative, Hum Pathol 2004;35:176) Chronic idiopathic myelofibrosis (Mod Pathol 2004;17:1513) Colorectal carcinoma (Mod Pathol 2004;17:197) Endometrial carcinoma (Gynecol Oncol 2006;103:1007) Esophageal adenocarcinoma (Hum Pathol 2006;37:861) Gastric carcinoma (Hum Pathol 2006;37:861) Hepatocellular carcinoma (BMC Cancer 2006;6:110) Meningioma (Acta Neuropathol 2007;114:147) Ovarian carcinoma (Int J Gynecol Cancer 2006;16:1789) Primary CNS lymphoma (J Neurooncol 2007;82:249) Prostate adenocarcinoma (Am J Clin Pathol 2007;127:572) and Squamous cell carcinoma of head and neck (Virchows Arch 2006;448:768), including tongue (Laryngoscope 2006;116:1175). Serum CD105 is associated with intrauterine growth restriction during pregnancy (J Clin Endocrinol Metab 2007;92:2831), preeclampsia (N Engl J Med 2006;355:992, Nat Med 2006;12:642), diabetic retinopathy (J Cell Mol Med 2005;9:692). Tissue CD105 is associated with progressive hepatic fibrosis in chronic HCV infection.
