Title: Studies of extracellular fibronectin matrix formation with fluoresceinated fibronectin and fibronectin fragments
Abstract: Fluorescein isothiocyanate conjugated human plasma fibronectin, 70-kDa collagen-binding, 60-kDa central, 60-kDa heparin-binding, 180-kDa heparin, collagen-binding fibronectin fragments and gelatin were used to study extracellular fibronectin matrix formation. Exogenous fibronectin, gelatin, 70-kDa collagen-binding and 180-kDa heparin, collagen-binding fragments were shown to be able to bind specifically to preexisting extracellular matrix of living fibroblasts. The results suggest that: (i) Fibronectin matrix formation may occur through a self-assembly process; (ii) the NH2-terminal part of fibronectin is responsible for fibronectin-fibronectin interaction during fibronectin fibril formation; (iii) plasma fibronectin may be the source for tissue fibronectin.
