ABSTRACT
Objective To examine the effects of mixed infusion of mesenchymal stem cells(MSCs) and bone marrow cells(BMCs) in the induction of chimerism and islet allograft tolerance.Methods BALB/C mouse was used as the recipient and C57BL/6 mouse was as the donor.BALB/C mice were rendered diabetic via injection of streptozotocin.The islet cells of donor mice were transplanted into the recipient mice under the capsule of kidney.Rat anti-mouse CD154 mAb was intraperitoneally injected to the recipient mice.All of recipient mice(n=25) were then randomly divided into five groups A group(received nothing),B group(donor MSCs),C group(donor BMCs),D group(donor BMCs and MSCs) and E group(donor BMCs and the third strain-derived MSCs).The chimerism level of donor cells and the survival time of islet grafts were compared among these five groups on 7,30d and 60d after transplantation.Results On 30d and 60d after islet transplantation,the chimerism levels of donor cells in D and E groups,in which the recipient mice received the mixed infusion of MSCs and BMCs,were significantly higher than that in C group,in which the recipient mice received BMCs infusion only,and the survival time of islet graft prolonged from 53.0?16.4d to 77.0?7.7d and 61.0?2.2d,respectively(P
