| Research Abstract |
Previously we reported that endothelial progenitor cell (EPC) transplantation could reduce established liver fibrosis and promote hepatic regeneration. In the current study, we investigated the hypothesis that gene transfer can be used to achieve phenotypic modulation of EPCs. Especially, we investigated the effect on regenerative properties of human hepatocyte growth factor (hHGF)-transduced EPCs in cirrhotic rat liver. In AdhHGF-transduced group, the degree of liver fibrosis was suppressed compared to those in AdLacZ-transduced group at 10 weeks after CCl_4 treatment. Ki67-positive hepatocytes in AdhHGF-transduced group were significantly increased. Moreover, serum total protein and albumin levels were significantly higher in AdhHGF-transduced group than those in AdLacZ-transduced group. In conclusion, this enhanced regenerative acceleration of transplanted EPCs by hHGF transfer will provide novel therapeutical strategy for hepatic regeneration in severe cirrhotic liver disease patients.
