Objective  To explore repair role of allogeneic bone marrow mesenchymal stem cells (BM-MSCs) transplantation on treating hepatic ischemia reperfusion injury (HIRI) in rats.
Methods  Ten rats were executed to get BM-MSCs, then BM-MSCs were cultured in vitro and dyed by 4,6-diamidino-2-phenylindole (DAPI). Models of 70% hepatic ischemia reperfusion injury were eatablished. Thirty two rats were randomly divided into sham operation group (Sham group), ischemia reperfusion group (I/R group), Vitamin C group (VC group), and BM-MSCs group. Serum samples were analyzed for ALT and AST, and hepatic tissue were for superoxide dismutase (SOD) and malondialdehyde (MDA). Liver sections were stain with hematoxylin and eosin (HE) for histological analysis, TUNEL staining was applied to detect hepatic apoptosis. Serum and tissues were both collected at 24 h after reperfusion.
Results  The isolated BM-MSCs maintained vigorous growth in vitro. Specific markers for MSCs antigens CD29 and CD44 were detected by flow cytometry, but antigens CD34 and CD45 were not be detected. Models of HIRI were stable, and BM-MSCs were detected around the periportal area by DAPI staining. Compared with I/R group, levels of ALT, AST, MDA, and AI in the VC group and BM-MSCs group decreased at 24 h after reperfusion (P<0.05), meanwhile SOD level increased (P<0.05). Compared with VC group, levels of ALT, AST, MDA, and AI in the BM-MSC group decreased at 24 h after reperfusion (P<0.05), meanwhile SOD level increased (P<0.05).
Conclusion  BM-MSCs could protect HIRI by alleviating oxidative stress and inhibiting cellular apoptosis.
