Comparative treatment efficiency of adipose and bone marrow derived allogenic mesenchymal stem cell transplantation in mouse models of liver fibrosis



Background: The application of mesenchymal stem cell (MSC) therapy in liver fibrosis treatment has been increasingly investigated in recent years. MSCs obtained from a variety of sources (e.g. bone marrow, umbilical cord blood and adipose tissue) have been studied and have achieved remarkable results. In this study, we compared the effects of adipose-derived mesenchymal stem cells (AD-MSC) transplantation with bone marrow-derived mesenchymal stem cell (BM-MSC) transplantation in a mouse model of liver fibrosis, induced by carbon tetrachloride (CCl4).

Methods: Eight-week old mice were treated with CCl4 for 11 weeks to induce liver fibrosis then 5×105 cells were transplanted into mice via the tail vein.

Results: After 21 days of transplantation, the results showed that the stem cell treated groups ameliorated better than the placebo group. MSC treated groups showed reduced AST and ALT levels, down-regulated expression of extracellular matrix (ECM) genes, and improved liver histopathology. Both sources of MSCs (bone marrow and adipose tissue) were effective in the mouse model of liver fibrosis.

Conclusion: Our results also indicated that AD-MSC transplantation in mice accelerated liver regeneration better than BM-MSC transplantation.
