To study the treatment effects of bone mesenchymal stem cells(BMMSCs)on the mice allergic encephalomyelitis,36 mice were randomly divided into three groups(control group,model group and BMMSCs group),12 for each group,and treated with different methods.After treatment for 8 weeks,expressions of IL-1,IL-2,IL-4,IL-6,IL-10,IL-12,TNF-α and IFN-γ of spinal cord tissues in mice were analyzed by RT-PCR and Western blot,and HE staining were performed to observe morphological changes of spinal cord tissues in mice.The RT-PCR and Western blot results showed as follows:compared to the control group,mRNA and protein levels of IL-1,IL-2,IL-12,TNF-α and IFN-γ significantly increased(p<0.05),while those of IL-4 and IL-10 significantly decreased(p<0.05)in the model group.In the BMMSCs group,the mRNA and protein levels of IL-1,IL-2,IL-12,TNF-α,IFN-γ were significantly downregulated(p<0.05),while those of IL-4 and IL-10 were significantly upregulated(p<0.05), compared with the model group.The HE staining results showed as follows:the structure of the spinal cord tissues and morphology of nerve cells were intact in the control group; in the model group,abundant inflammatory cells appeared in the spinal cord tissues; in contrast,no obvious inflammatory cells were observed in the BMMSCs group.Taking together,it is suggested that BMMSCs have therapeutic effect on experimental allergic inflammatory response in mice,and the mechanism involves inhibiting the expressions of inflammatory cytokines and reduce the damage to the spinal cord.
