Objective:To study the in vitro immunosuppression of interleukin-10(IL-10) modified bone marrow mesenchymal stem cells(BMMSCsIL-10). Methods:IL-10 was cloned by RT-PCR and was used to construct pLNCX-IL-10. The constructed retrovirus was transfected into rat BMMSCs. T lymphocyte subsets in vitro influenced by BMMSCsIL-10 were detected by flow cytometry. Effects of BMMSCsIL-10 and its culture supernatant on in vitro mixed heterologous T lymphocyte proliferation were detected by CCK-8. Results:BMMSCsIL-10 significantly reduced CD4+ T and lowered the ratio of CD4+/CD8+,more intense than BMMSCs(P=0.000). BMMSCsIL-10 and its culture supernatant significantly inhibited T lymphocyte proliferation,more intense than BMMSCs(P=0.000). Conclusions:IL-10 modification can enhance the in vitro immunosuppressive effect of BMMSCs.
