摘　　要：Objective To study the role of IFN-γ/IL-10 cytokines protein expression of human decidual stromal cells（DSC） vitro. on IL-10 receptor gene and in human early pregnancy in vitro. Methods Human DSC was isolated and cultured in vitro, and the expression of IL-10R1 and IL-10R2 gene was analyzed after cells had been treated with TH2-type cytokines IL-10 and TH1-type cytokines IFN-γ within 60 rain with semiquantitative reverse transcriptase-PCR, then the influence of IL-10 and IFN-γ on expression of IL-10R protein was examined by first trimester DSC using flow cytometry. In addition, the vitality of DSC was detected by MTT. Results IL-10R1 mRNA levels of DSC treated with IL-10 （10 ng/ml） reached the peak level within 15 rain, and were significantly lower at 30 rain, then were not detected at 45 min. The expression of IL-10R1 were induced to moderate level by IFN-γ（10 ng/ml） within 30 rain, and reduced to undetected levels at 60 min. There was no significant difference of IL-10R2 expression （P〉0.05） between treated and not with the abovementioned cytokines. The IL-10R protein expression and vitality of DSC were significantly enhanced by IL-10 （10 ng/ml） and IFN-γ （10 ng/ml） which treated DSC 48 h （P〈0.05）. Coneclusion IL-10 and IFN-γ may play an important role of biologic function in early pregnancy by influencing IL-10R expression of DSC.Objective To study the role of IFN-γ/IL-10 cytokines protein expression of human decidual stromal cells（DSC） vitro. on IL-10 receptor gene and in human early pregnancy in vitro.
