Abstract:

Objective To obseve the rapair effect of hepatic progenitor cells (HPCs) transplantation on the liver of mouse models of acute liver failure induced with different concentrations of carbon tetrachloride (CCl4), and to construct one ideal mouse model of acute liver failure for evaluation on the efficacy of HPCs transplantation. Methods 96 ICR mice were randomly divided into nine groups: blank control group, negative control groups (0.1% CCl4 group, 0.5% CCl4 group, 2.0% CCl4 group and 10.0% CCl4 group) and experimental groups (0.1% CCl4 + HPCs group, 0.5% CCl4 + HPCs group, 2.0% CCl4 + HPCs group and 10.0% CCl4 + HPCs group).Normal saline was given to the mice in blank control group by intragastric administration, and the mice in negative control groups and experimental groups were administrated with different concentrations of CCl4.One day later, the mice in experimental groups were injected with HPCs from spleen, and the mice in negative control groups were given the same dose of normal saline.14 d after the injection of HPCs, the survival rate, liver index, the activities of serum alanine aminotransferase(ALT) and aspartate aminotransferase(AST), the histopathological changes, the distribution of exogenous hepatocytes and the expression levels of cytokeratin 18(CK18) and albumin (ALB) were detected. Results Compared with blank control group, the survival rates, liver indexes and the activities of serum ALT and AST in 0.1% CCl4 group and 0.5% CCl4 group had no significant changes(P>0.05);the effective treatment of HPCs transplantation was not observed because of self-repairing.Compared with 2.0% CCl4 model group, the activities of serum ALT and AST and liver index in 2.0% CCl4 + HPCs group were significantly decreased(P<0.01), and the survival rate was increased(P<0.01);the liver cell regeneration and a large number of exogenous hepatocytes were found by pathological detection in 2% CCl4 + HPCs group;the therapy of HPCs transplantation was effective.All mice died in 2 d in 10.0% CCl4 group and 10.0% CCl4 + HPCs group, and the therapeutic efficacy of HPCs was not observed. Conclusion HPCs transplantation can increase the survival rate of the model mice of acute liver failure, improve the activities of ALT, and AST and repair the hepatic injury;HPCs transplantation treatment is effective on the mouse model of 2.0% CCl4-induced acute liver failure.
