  • Objective To investigate the effect of intraperitoneal transplantation of human liver-derived stem cells in the prevention and treatment of alcoholic fatty liver disease in mice. Methods A total of 30 male C57 BL/6 mice were randomly divided into blank control group ( group N) , model control group ( group M) , and stem cell transplantation group ( group S) . The mice in group N were fed a normal diet, and those in the other two groups were fed Lieber-DeCarli alcohol liquid diet; at the same time, the mice in group S were given intraperitoneal transplantation of human liver-derived stem cells twice a week. After six weeks of intervention, body weight and liver index were measured, and the serum levels of alanine aminotransferase ( ALT) , aspartate aminotransferase ( AST) , total bilirubin ( TBil) , total cholesterol ( TC) , triglyceride ( TG) , high-density lipoprotein cholesterol ( HDL-C) , and low-density lipoprotein cholesterol ( LDL-C) were also measured. The levels of TG and non-esterified fatty acid ( NEFA) in the liver were measured, and liver pathological examination and oil red O staining of the liver were performed. One-way ANOVA was used for comparison of continuous data between multiple groups, and the SNK-q test was used for further comparison between two groups. Results There were significant differences in the serum levels of ALT, AST, TG, TC, and HDL-C and the content of TG and NEFA in the liver between the three groups ( F = 66. 94, 7. 15, 8. 02, 18. 64, 3. 86, 23. 14 and 30. 49, all P < 0. 05) , Compared with group N, group M showed significant increases in levels of ALT, AST, and TG in serum and levels of TG and NEFA in liver tissue ( all P < 0. 05) . Group S had significantly lower levels of ALT, AST, and TG in serum and levels of TG and NEFA in liver tissue than group M ( all P < 0. 05) . Liver HE staining and oil red O staining showed that group S had a significantly lower degree of liver steatosis than group M. Conclusion Intraperitoneal transplantation of human liver-derived stem cells has a marked effect in the prevention and treatment of alcoholic fatty liver disease in mice.
