initial studies described the significance of heparan sulfate proteoglycans of balb/c 3t3 cells in their adhesion on fibronectin matrices , including their binding to multiple domains in fn , the importance of this binding in microfilament and close contact formation , and the cooperativity of both hs-pg and 140k glycoprotein integrin 's binding to fn to achieve tight-focal contacts under cells .
