Fibronectin (FN) is a multifunctional, extracellular matrix glycoprotein composed of two nearly identical disulfidebound polypeptides of molecular weight 220 kDa. areful analysis of the fibronectin molecule indicate that it contains several functionally and structurally distinct domains which may bind to cell surfaces, collagen, fibrinogen or fibrin, complement, glycosaminoglycans, proteoglycans and heparin. Fibronectin, some of which exhibit restricted tissue distribution or association with malignancies. It has been shown that Myofibroblast phenotype formation correlates with the occurrence of glycosylated Fibronectin and Fibronectin splice variants in Dupuytren’s disease.
