Assembly of fibronectin into the provisional fibrillar matrix of embryonic tissues and wounds is a complicated process by which the intracellular cytoskeleton determines the pattern of assembly of extracellular matrix and vice versa. Assembly is restricted to dimeric fibronectin molecules with intact N-terminal modules and occurs at specialized cell surface sites. Cellular display of assembly sites is labile and requires that cells be under tension and have functional beta 1 integrins. Lysophosphatidic acid (LPA) an intermediate for de novo lipid biosynthesis and a product of platelet activation, is a powerful serum modulator of fibronectin assembly.
