Title: Identification of a fibronectin receptor specific for rat liver endothelial cells

Journal Article · · Experimental Cell Research; (USA)

Antibodies raised against the fibronectin receptor of rat hepatocytes recognized one protein in immunoblotting of solubilized rat liver endothelial cells (LEC). The antibodies specifically precipitated a 200-kDa protein together with the 135-kDa component from {sup 125}I-labeled LEC. Spreading of LEC on fibronectin, but not on laminin or collagen, was inhibited by monovalent Fab fragments of the antibodies, implicating that the 135/200-kDa complex is a specific fibronectin receptor. The results indicate that LEC, hepatocytes, and fibroblasts of rat carry different fibronectin receptors, suggesting that the interaction of fibronectin with these cells may have different functional roles.
