Fibronectin is an extracellular matrix (ECM) component and is one of the primary cell adhesion molecules (1). It is composed of multiple homologous repeats and contains many functional domains. The occurrence of different isoforms is due to alternative mRNA splicing of the ED-A, ED-B and III-CS regions and subsequent post-translational modification. Although non-reactive with adhesion receptors in its soluble state, Fibronectin is highly adhesive when on the surface (2). Polymerization of Fibronectin into ECM must be tightly regulated to ensure appropriate adhesive proporties upon ECM formation. Because of its ability to interact with many ligands (e.g. cells, heparin, fibrin, collagen, DNA, immunoglobulin), Fibronectin plays an important role in normal morphogenesis, including cell adhesion, migration, differentiation, and specific gene expression (3 - 6).
