Abstract:
BACKGROUND:A cell mass from bone marrow can transform into oval cells and then differentiate into hepatocytes and biliary tract endothelial cells.It will bring a new hope for repairing irreversible damage of the liver.OBJECTIVE:To review several recent research results of the differentiation of bone marrow stem cells into hepatocytes.RETRIEVAL STRATEGY:A computer-based search was conducted in Pubmed and HighWire for English articles about bone marrow stem cells for liver ailments published between January 1999 and June 2007 with the key words of "bone marrow stem cells,mesenchymal stem cells,hemopoietic stem cells,hepatocytes,hepatic fibrosis,hepatic cirrhosis".Meanwhile,Vip Database was undertaken to identify the relevant articles on bone marrow stem cells in the treatment of hepatic cirrhosis and hepatic fibrosis published between January 1999 and June 2007 with the key words of "bone marrow stem cells,mesenchymal stem cells,hemopoietic stem cells,hepatocytes,hepatic fibrosis,hepatic cirrhosis" in Chinese.The data were selected primarily,and then quotations of each article were checked.Inclusive criterion:The articles related to curing hepatic fibrosis and hepatic cirrhosis with bone marrow stem cells were selected.Exclusive criteria:the articles with repetitive research or Meta analysis were excluded.A total of 49 related English articles and 42 Chinese articles were collected,34 literatures of them in accordance with the inclusive criterion were reviewed.Fifty-seven articles with old or repetitive articles were excluded.LITERATURE EVALUATION:Of the 34 inclusive articles,18 were on transplanting in vivo,12 were about cultivation and induction in vitro and 4 were about the problems and prospect.DATA SYNTHESIS:Bone marrow stem cells include mesenchymal stem cells and hemopeietic stem cells,which are characterized by plasticity.Growth factors in vitro and special microenvironment in vivo could induce the differentiation of bone marrow stem cells into the precursor of hepatocytes and mature hepatocytes.Moreover,hepatic function could be improved obviously.The superiorities of bone marrow stem cells included affluent source,low cost,little injury,without embolism and graft rejection in autologous transplantation,which offer a new style for curing hepatic diseases.Bone marrow stem cells would be the cell resource of artificial liver.CONCLUSION:Using bone marrow stem cells therapy for all kinds of refractory hepatopathy,such as hepatitis,liver cirrhosis and hepatoma,indicates a great achievement in clinic.
