Description
Fibronectin is a major component of the extracellular matrix that binds to integrins, cell surfaces and various compounds including collagen, fibrin, heparin, DNA and actin. It occurs in two main forms: plasma and cellular fibronectin. EDA (Extra Domain A)-containing cellular fibronectin (EDA-FN) plays a major role in cell adhesion, growth, migration and differentiation and it is important for processes such as wound healing and embryonic development. It is associated with fibroblast differentiation by increasing α-SMA expression, collagen deposition, cell contractility and focal adhesion kinase (FAK) activation. EDA-FN promotes cell spread by interacting with the integrins α5-β1, α4-β1 and α9-β1 and has been shown to promote angiogenesis, lymphangiogenesis and metastasis of colorectal tumors. In transformed or tumor-derived cells the EDA segment is about 10-times higher than in fibronectin from normal fibroblasts and it may therefore be a significant marker for malignancy.
