Abstract

Structural differences between platelet and endothelial cell thrombospondin (TBSP) were found in two protease-resistant domains (70 and 18 kDa). The 70 kDa fragment is involved in the binding of TBSP to fibrinogen and the 18 kDa fragment in the attachment to various cultured cells. Despite these structural differences, platelet and endothelial cell TBSP bound with the same affinity to fibrinogen and mediated the attachment of smooth muscle cells but not of endothelial cells.
