摘要: Objective To investigate the possibility of flk-1 + Sca-1 − bone marrow–derived mesenchymal stem cells (bMSCs) to induce stable mixed chimerism and donor-specific graft tolerance. Methods Allogeneic bMSCs syngeneic marrow (BM) were cotransplanted into lethally irradiated (8.5 Gy) recipient mice. FACS was used analyze 150 days later. Donor-type skin transplantation performed observe immunotolerance in Mixed lymphocyte reaction (MLR) mitogen proliferative assays evaluate response splenocytes from Results More than 5% donor-derived CD3 detected Long-term survival donor-type grafts observed. MLR showed that mice had low immunoresponse donor but retained normal ConA-induced compared with Conclusion Our results show for first time induction hematopoietic can be achieved allogeneic bMSC transplantation, which leads permanent host long-term acceptance.
