Extracellular glycoprotein that plays an important role in many physiological processes, including wound healing and the migration and adhesion of cells (fibra for "fiber"; nexus for "linkage").

The fibronectin contains binding regions for fibrin, heparin and collagen as well as a cell binding region.
