Autologous bone marrow stem cell transplantation for liver cirrhosis via the hepatic artery in rabbits

BACKGROUND:How to make more transplanted bone marrow stem cells stay and differentiate in the liver is an important issue, which is also crucial for treatment of liver cirrhosis via the hepatic artery.OBJECTIVE:To investigate the therapeutic effect of autologous bone marrow stem cell transplantation via the hepatic artery on liver cirrhosis. METHODS:Thirty New Zealand white rabbits were equivalently randomized into normal control, stem cell transplantation and model groups. Animal models of liver cirrhosis were made in the latter two groups. Then, model rabbits in the stem cell transplantation group were subjected to autologous bone marrow stem cell transplantation via the hepatic artery. Liver function of rabbits was detected in 1, 2, 4, 8, 10 weeks after cell transplantation, and pathological detection of the liver was performed in the 10th week. RESULTS AND CONCLUSION:At 10 weeks after cell transplantation, the liver function of the rabbits was improved significantly compared with the model group, including reduced activities of serum alanine aminotransferase, total bilirubin and aspartate aminotransferase, shortened activated partial thromboplastin time, and increased albumin level (P < 0.05). Pathological examination of the liver showed that the liver cells in the stem cell transplantation group were intact with no obvious edema and still had the structure of the pseudolobule, and compared with the model group, the degree of liver fibrosis was significantly reduced in the stem cell transplantation group. Our experimental results show that the transplantation of autologous bone marrow stem cells via the hepatic artery has a certain therapeutic effect on liver cirrhosis by increasing the body albumin content in a short time and improving the liver function.
