Chinese Journal of Immunology 2000;0(08):-
Objective:To examine the effect of cyclosporine A(CsA) on the differentiation of Th17 cells from splenocytes after stimulation with anti-CD3 mAb+IL-23.Methods:Total splenocytes were cultured with anti-CD3 mAb alone or anti-CD3 mAb plus IL-23 in the presence or absence of different concentrations of CsA.After stimulation,production of IL-17 and IFN-? was assayed by ELISA.The subsets of IL-17-producting T cells were examined at single-cell level by flow cytometry.Results:The splenocytes stimulated with anti-CD3 mAb alone could induce low level of IL-17 production and addition of IL-23 could promote high level of IL-17 in a dose-dependent manner.CsA inhibited the differentiantion of Th17 cells from splenocytes stimulated with anti-CD3 mAb+IL-23 in a dose-dependent manner.Kinetic studies indicated that CsA also inhibited the differentiantion of Th17 cells from activated T cells stimulated by anti-CD3 mAb+IL-23 for 48 hours.In addition,CsA inhibited production of IFN-? and IL-2.The analysis of subsets of T cells demonstrated that CD4+T cells but not CD8+T cells produced IL-17.Conclusion:CsA can inhibit Th17 cell differentiation.This observation shed a new light on the potential mechanisms for the immunosuppressive and anti-inflammatory functions of CsA and provideds a theoretical and experimental foundation for clinical application.

BACKGROUND: Non-adherent mesenchymal stem cells (NA-MSCs) can form colony forming unit of fibroblasts and induce the differentiation into adipocytes, osteoblasts, and chondrocytes. OBJECTIVE: To determine the effect of epithelial growth factor (EGF) on colony formation of fibroblasts and differentiation into neuron-like cells from NA-MSCs.METHODS: Bilateral femur and tibia as well as total MSCs were separated, and repeated-transfer was employed to purify NA-MSCs. The fifth-passage total MSCs and NA-BMCs were induced in a medium containing EGF and basic fibroblast growth factor (b-FGF) for 2 weeks. Colony unit formation of fibroblasts, effect of EGF on colony-forming unit of fibroblasts, and relative protein expression detected by toluidine blue and immunocytochemical staining were observed. RESULTS AND CONCLUSION: Both total MSCs and NA-BMC could generate colony-forming unit of fibroblasts. After treatment of EGF, colony-forming unit of fibroblasts from NA-BMC was increased significantly. Immunocytochemical staining demonstrated that two weeks later both neuro-specific NeuN and NF-200 were observed in total MSCs and NA-BMC; while, toluidine blue staining indicated that neuron-specific Nissl body was observed in some cells. EGF can effectively promote colony-forming unit of fibroblast from NA-BMC, and repeated-transfer NA-BMC can induce differentiation into neuron-like cells.

BACKGROUND: Non-adherent mesenchymal stem cells (NA-MSCs) can form colony forming unit of fibroblasts and induce the differentiation into adipocytes, osteoblasts, and chondrocytes.OBJECTIVE: To determine whether non-adherent mesenchymal stem cells (NA-MSCs) in adult mouse bone marrow could differentiate into neuron-like cells in cerebral ischemic region.METHODS: Bilateral femur and tibia of β-Gal transgenic mice was separated, and repeated-transfer was used to collect the fifth-passage purified NA-MSCs which were adjusted at concentration of 1×10~(12)/L Middle cerebral artery occlusion was established in the two groups. After 7 days, 3 μL fifth-passaged NA-MSCs suspension was injected into cerebral ischemic region in the transplantation group, while an equal amount of saline was injected into model group. Survival, distribution, and differentiation of donor cells in cerebral ischemic region were observed at 8 weeks after transplantation.RESULTS AND CONCLUSION: LacZ staining showed that donor cells could express β-Gal protein after 8 weeks and survived in the ischemic region. Simple and double immunohistochemical staining indicated that β-Gal-positive donor cells were detected in necrotic region and at necrotic edge of ischemic model. Additionally, partial cells could express neuro-specific NeuN protein and glial cell-specific GFAP. NA-MSCs are able to survive and migrate in cerebral ischemic region; moreover, partial NA-MSCs can differentiate into mature neuron-like cells or glial cells which participate in repairing brain injury.
