Background: CD90/Thy1

CD90, also known as Thy1, is an approximately 25-35 kDa glycoprotein that mediates cellular adhesion and exerts wide ranging effects in different tissues (1, 2). CD90 is expressed on hematopoietic progenitor cells, neurons, and activated vascular endothelial cells (3-5). Its species-specific expression in lymphoid cells allows its use as a thymocyte and pan T cell marker in mouse but not in human (1). CD90 can form dimers and higher order multimers (6). It binds to heparin, the proteoglycan Syndecan-4, and Integrins alpha M beta 2, alpha V beta 3, and alpha V beta 5 (5, 7-10). Through these interactions, CD90 inhibits neurite outgrowth (4), promotes astrocyte adhesion (7), mediates the adhesion and extravasation of leukocytes and melanoma cells (5, 9), supports the Thrombospondin-1 induced disassembly of fibroblast focal adhesions (11), and inhibits the activation of latent TGF-beta 1, myofibroblast differentiation, and lung fibrosis (10). Human Thy-1 shares 63% and 66% amino acids similarity with mouse and rat homolog.
