abstract：:Fibronectin mediates the adhesion of cells to collagen by first binding to the collagen substrate, followed by attachment of the cells to the fibronectin-collagen complex. Bovine brain gangliosides were found to block fibronectin-mediated cell adhesion to collagen in a concentration-dependent manner. The gangliosides ...
