RESUMO
BACKGROUND:Studies have found that both bone marrow mesenchymal stem cels and umbilical cord mesenchymal stem cels have therapeutic effects on liver failure, but little is reported on adipose-derived mesenchymal stem cel transplantation for treatment of liver failure. OBJECTIVE:To discuss the therapeutic effect of adipose-derived mesenchymal stem cel transplantation on rat liver failure. METHODS: Forty-five Sprague-Dawley rats were equaly randomized into transplantation, model and control group. Except the control group, animal models of liver failure were made by intraperitoneal injection of D-galactosaminein in the transplantation and model groups. One week after modeling, rats in the transplantation group were given 1 mL of adipose-derived mesenchymal stem celsvia the tail vein. RESULTS AND CONCLUSION:Adipose-derived mesenchymal stem cell transplantation successfully upregulated alanine aminotransferase and aspartate aminotransferase levels, and moreover, neatly arranged liver cells, reduced inflammatory cells and intact hepatic lobule were shown on B ultrasound after cell transplantation. All these findings indicate that adipose-derived mesenchymal stem cell transplantation has therapeutic effects on rat liver failure by improving rat’s liver function and pathological changes.
