Abstract
The proliferative response of hepatocytes in vivo can be induced by two mechanisms: severe damage to hepatic tissue results in regenerative growth and so-called primary hepatocyte mitogens can initiate liver cell proliferation without preceding loss of parenchyma. The regulation of the two responses is quite different. The decreased regenerative response of cirrhotic/fibrotic liver is well known, and is a severe obstacle to surgery of the diseased liver. In the present experiments we investigated the efficiency of a primary hepatocyte mitogen 1,4-Bis[2-(3,5-dichloropyridyloxy)]benzene (TCPOBOB) on two different liver cirrhosis/fibrosis models in mice induced by chronic administration of CCl(4) and thioacetamide respectively. BrdU incorporation and cyclin A expression established clearly that there is a reduced but still powerful mitogenic response of the fibrotic livers. Therefore, primary hepatocyte mitogens appear to be suitable to be used to rescue the regenerative response of cirrhotic livers.
