ABSTRACT
This study was aimed to investigate the expression of radioresistant genes survivin and HO-1 in mesenchymal stem cells (MSC). Human bone marrow MSC were isolated and enriched by Fircoll density gradient centrifugation, then identified by flow cytometry. MSC were induced with dexamethasone, insulin, 3-isobutyl-1-methyl-xanthine (IBMX) and indomethacin to differentiate into adipocytes. Then the expression of survivin and HO-1 in MSC was detected by RT-PCR. The results indicated that the expressions of surface antigen CD34 and HLA-DR in MSC in vitro were negative while the expressions of CD44 and CD71 were positive. MSC could be differentiated into adipocytes by inductor. RT-PCR showed the expression of radioresistant genes survivin and HO-1 in MSC. It is concluded that MSC have lower sensitivity to radiation, which may associate with the expression of radioresistant genes survivin and HO-1 in MSC.
