Hepatic fibrosis is now regarded as a common response to chronic liver injury; regardless of its nature (viral infections, alcohol abuse and metal overload). It is also characterized by excessive deposition of extracellular matrix (ECM) components. The ECM is a dynamic complex of macromolecules that includes collagens, glycoproteins, and proteoglycans, such as laminin and fibronectin; it has been shown that it does not only support the tissue structure, but also plays a major role in cell adhesion, proliferation, and differentiation. Remodelling of the ECM may be the signal that facilitates lobular reorganization during liver regeneration after a liver injury. Much work has been done concerning the ECM synthesis and protein contents.
