Abstract: Objective To observe the therapeutic effects of co-transplanted umbilical cord blood stem cells and bone marrow stem cells for rats with acute liver failure induced by D-galactose. Methods Mononuclear cells isolated from umbilical cord blood and bone marrow of rats were cultured in medium containing hepatocyte growth factor(HGF) and stem cell factor(SCF) for 3 weeks,and the expression of hepatocyte markers,such as AFP and ALB,were detected by immunocytochemistry;A rat model of acute liver failure was established by D-galactose injection(1.4 g.kg-1,intraperitoneally) for 24 h. Rats with acute liver failure were subjected to transplantation of bone marrow stem cells,umbilical cord blood stem cells,and umbilical cord blood stem cell mixed with bone marrow stem cell,or an equal amount of saline per day for seven days. The survival rates,liver function and pathological changes in liver were studied. Results Bone marrow stem cells and umbilical cord blood stem cells were successfully proliferated and differentiated into hepatocytes in vitro by stimulation of HGF and SCF. The 9-day survival rates of rats with acute liver failure in umbilical cord blood stem cell,bone marrow stem cell and mixed stem cell transplantation group were 55.6%,50.0% and 77.8%,respectively,all of which were markedly higher than that in rats treated with saline(16.7%,P<0.01);The 9-day survival rate of rats in mixed cell transplantation group was significantly higher than that of rats in umbilical cord blood stem cell or bone marrow stem cell alone (P<0.01). Conclusions Bone marrow stem cell and umbilical cord blood stem cell transplantation improve liver function of rats with acute liver failure,and combinational transplantation of these two cells is efficient.
