小鼠异体Sertoli细胞诱导胰岛移植免疫耐受的作用

Objective To study whether the sertoli cell allograft can achieve the immunotolerance and protect the co-transplant islet allograft on the heterotopic situation. Methods The diabetic C57 mice were used as recipients, and healthy BALB/C mice as islet donors,respectively. Healthy BALB/C and C57 mice were used as testis sertoli cell donors. The recipients were randomly divided into 4 groups,6 mice in each group : group A: only transplant with islet allograft;group B: co-transplant with islet allograft and serto-li isograft;group C:co-transplant with islet allograft and sertoli allograft;group D:sham-operated group. The blood and urine glucose levels in the models, and the survival time of the graft were observed. Results The mean survive time of graft in groups A, B, and C was (6.50±2.35 ), (55.67±4.84), and (51.33± 5.05 ) days respectively. In group D, blood glucose level was abnormal. The hyperglycemia of the diabetic C57 mice could be reversed by the transplant methods of groups B and C. The mean survival time in groups B and C was longer than in group A P < 0.05, but there was no significant differences between groups B and C,P > 0.05. Conclusion The sertoli cells can induce local immunotolerance and protect the co-transplant islet allograft. Sertoli cell isograft can obtain the same local immunotolerance as the sertoli cell allograft.
