Effect of bone marrow mesenchymal stem cells transplantation on the expression of CD163 and interleukin-10 in rats with acute hepatic liver failure / 中国组织工程研究

ABSTRACT

BACKGROUND:Studies have shown that bone marrow mesenchymal stem cells have the ability to persistently generate hepatocytes and biliary cells, and thus in the repair process of liver injury, replenish the reduced number of hepatocytes due to damage and participate in damaged liver structure. OBJECTIVE:To investigate the effect of bone marrow mesenchymal stem cells transplantation on acute liver failure and the expression of CD163 and interleukin-10 in rat serum and liver tissue. METHODS:D-galactose and lipopolysaccharidewere used to make acute liver failure models in 60 Sprague-Dawley rats. Then, the rats were divided into control group and transplantation group. Bone marrow mesenchymal stem cells at passage 3 were injected through tail vein in the transplantation group, and normal saline was injected in the control group. After transplantation 24, 120, 168 hours, serum samples and liver tissues were col ected. RESULTS AND CONCLUSION:After transplantation 120 and 168 hours, the serum alanine transaminase and aspartate aminotransferase activities of the transplantation were significantly lower than those of the control group (P<0.05). In the transplantation group the apoptotic index was stil lower compared with the control group, and the difference was significant (P<0.05). The levels of CD163 and interleukin-10 in the serum and liver tissue in the transplantation group were decreased significantly compared with the control group (P<0.05). The results suggested that there were highly significant correlations between CD163 and interleukin-10 (P<0.01). Bone marrow mesenchymal stem celltransplantation has a therapeutic effect on acute liver failure rats. CDl63 and interleukin-10 play a very important role in the pathogenesis of acute liver failure, which can be used as sensitive serum marker proteins for diagnosis and prognosis of acute liver failure.
