Cell adhesion to the extracellular matrix is important in many biological processes. Furthermore, fibronectin has two subunits that vary in size (235-270 kDa) as a result of alternative splicing. An important difference between fibronectin and laminin is the place of occurence. CONCLUSION: It can be concluded that when liver biopsy is contraindicated, the serum levels of laminin, hyaluronic acid, and fibronectin can be considered It is a major component of the basal lamina, which is one of the layers of the basement membrane. Fifteen laminin trimers have been identified. It is formally called the “cold-insoluble globulin”, or CIg. In vitro cell adhesion to matrix proteins and to other \`adhesion' proteins is generally measured on plastic culture substrates. Laminin, a basement membrane glycoprotein isolated from cultures of mouse endodermal cells and rat yolk sac carcinoma cells, promoted the attachment of liver cells obtained from regenerating mouse liver. The secreted or the soluble fibronectin polymerizes to higher order fibrils that are insoluble and occur in the ECM. 19 Laminin, on the other hand, is located only in the basement membrane, 20 where it binds to and promotes the adhesion of cells to collagen type IV. In muscle, it binds to alpha dystroglycan and integrin alpha7—beta1 via the G domain, and via the other end it binds to the extracellular matrix. Also, both are crucial in cell adhesion, migration, growth, and differentiation. Five acrylate IOLs were analyzed for fibronectin, 6 for vitronectin, and 1 each for laminin and collagen type IV. Besides, a defective fibronectin can cause cancer and fibrosis while defective laminin can cause muscular dystrophy, defects of the kidney filter, and lethal skin blistering disease. Fibronectins are responsible for wound healing since they are involved in blood clotting. were compared, and the area under curves for serum levels of laminin, hyaluronic acid, and fibronectin, as indicators of diagnostic accuracy, were 0.89, 0.82, and 0.73, respectively. Thus, this summarizes the difference between fibronectin and laminin. The mean albumin –creatinine ratio was significantly higher (p<0.001) among type 2 DM (1.99 0.78 mg/mmol) compared to the control (0.12 0.01 mg/mmol).
