Abstract
Liver fibrosis,which is the only way from chronic liver disease to cirrhosis,is the result of extracellular matrix(ECM) excessive deposition in the liver. The ECM is mainly synthesized by the activated hepatic stellate cells(HSC),and its degradation is regulated by the matrix metalloproteinase tissue inhibitor-1(TIMP-1),therefore HSC and TIMP-1 play important roles on development of hepatic fibrosis. Recently,antifibrotic studies about HSC and TIMP-1 have been a hot spot,this article reviewed the biological characteristics of HSC and TIMP-1 and their effects on liver fibrosis.
