ABSTRACT
BACKGROUND:The non-specific immune suppression method is generaly used for treatment of systemic lupus erythematosus, but poor prognosis, such as infection and high recurrence rate, exists. OBJECTIVE:To evaluate the therapeutic effect of bone marrow mesenchymal stem cel transplantation on systemic lupus erythematosus in mice. METHODS:Sixteen mice with systemic lupus erythematosus were equivalently randomized into control and experimental groups, or then subjected to passage 3 bone marrow mesenchymal stem cel transplantation or the equal volume of normal saline via the tail vein, respectively. Mouse urine samples were colected to detect urine protein levels by Bradford method. Blood samples from the tip of the mouse tail were extracted to detect serum anti-ds-DNS antibody concentration by radioimmunoassay. Mouse kidney tissues were taken and observed pathohistologicaly through hematoxylin-eosin staining and immunohistochemistry staining under microscope. Flow cytometry was used to detect the expression of CD4+CD25+T cels in the inner canthus blood, fresh spleen and thymus. RESULTS AND CONCLUSION:Within 10 weeks after cel transplantation, the urine protein levels in the two groups were gradualy increased, and the rising velocity was higher in the control group than in the experimental group. From the 4th to 10th week, the urine protein levels in the experimental group were significantly lower than those in the control group (P 0.05). The serum anti-ds-DNA antibody concentration in the experimental group was significantly lower than that in the control group (P < 0.05). Taken together, bone marrow mesenchymal stem cel transplantation can improve the pathological damage in systemic lupus erythematosus mice, and has a certain therapeutic effect on systemic lupus erythematosus.
