HGF and Cirrhosis: To further study the impacts of HGF on the repair potential of grafted DPSCs in cirrhosis, histopathological analyses were conducted on healthy rats (Control), sham-treated rats with cirrhosis (CCl4/Saline) and rats receiving grafts of wild-type DPSCs (DPSC), blank lentiviral vector (CCl4/DPSC-Vector)-transduced DPSCs or hHGF-lentiviral vector (CCl4/DPSC-HGF)-transduced DPSCs for 6 weeks.
