fibronectin could also be crosslinked to types i and iii collagen , but only at 37 degrees c. alpha 1 ( i ) -cb7 , alpha 1 ( i ) collagen chains , type i collagen , type iii collagen , and fibrin all blocked cross-linking between 125i-alpha 1 ( i ) -cb7 and fibronectin . alpha 1 ( i ) -cb7 blocked cross-linking between fibronectin and fibrin .
