Transforming Growth Factors β1 and α in Chronic Liver Disease

Abstract
Cirrhosis is a diffuse process of hepatic fibrosis and regenerative nodule formation of unknown pathogenesis. Transforming growth factor (TGF) β1 induces the production of extracellular matrix proteins by liver cells and has been implicated in the pathogenesis of hepatic fibrosis in laboratory animals. TGFα is a hepatocyte mitogen that participates in liver regeneration.
