Abstract Background Mesenchymal stem cells (MSCs) have been utilized in treating acute graft-versus-host disease (aGvHD) as they show strong immunosuppressive capacity, but the mechanisms are not well defined.Methods In this study, we demonstrated that microRNA-223 (miR-223) derived from exosomes secreted by human umbilical cord mesenchymal stem cells (huc-MSCs) and murine compact bone mesenchymal stem cells (mb-MSCs) could inhibit aGvHD progression by reducing the migration and homing of donor T cells in aGvHD mice.Results MiR-223 was one of the conserved microRNAs highly expressed in huc-MSCs exosomes and mMSCs exosomes, which was identified by high-throughput sequencing. MiR-223 derived from MSC exosomes showed enhanced immunosuppressive capacity, as it could inhibit expression of the target gene ICAM-1 and restrain adhesion and migration of T cells in vitro. Moreover, miR-223Agomir was effective in reducing the inflammatory reaction, and declining the donor T cells infiltration into the spleen, liver and intestine in aGvHD mice. Subsequently, it could alleviate aGvHD symptoms. Taken together, the MSC exosome derived miR-223 could attenuate aGvHD in mice through regulating ICAM-1 expression.Conclusions Our results unveil a new role for MSC exosomes derived miR-223 in the treatment of aGvHD.

Abstract Mesenchymal stem cells (MSC) from adult bone marrow have the capacity to differentiate into several mesenchymal tissues and inhibit T-cell alloreactivity in vitro. Within the EBMT MSC expansion consortium we have used MSC to treat grades III–IV acute graft-versus-host disease (GvHD) in 40 patients. The MSC dose was median 1.0 (range 0.4–9) 10^6 cells/kg body weight of the recipient. No side-effects were seen after MSC infusions. Nineteen patients received one dose, 19 patients received two doses, two patients received three and five doses respectively. MSC donors were in five cases HLA-identical sibling donors, 19 haploidentical donors and 41 third-party HLA-mismatched donors. Among the 40 patients treated for severe acute GvHD, 19 had complete responses, nine showed improvement, seven patients did not respond, four had stable disease and one patient was not evaluated due to short follow-up. Twenty-one patients are alive between six weeks up to 3.5 years after transplantation. Nine of these patients have extensive chronic GvHD. One patient with ALL has recurrent leukaemia and one patient has denovo AML of recipient origin. We conclude that MSC have immunomodulatory and tissue repairing effects and should be further explored as treatment of severe acute GvHD in prospective randomized trials.

Abstract Background Mesenchymal stem cells (MSCs) have been considered as a promising strategy for the prevention and treatment of acute graft-versus-host disease (aGVHD), but the mechanism of MSCs ameliorating GVHD is still not fully understood. A few studies suggested that MSCs ameliorated GVHD via protecting and repairing the function of thymus. Methods Twenty refractory aGVHD patients receiving MSCs treatment were enrolled in this study, and twenty grade II to IV aGVHD patients treated without MSCs were matched as non-MSCs group. MSCs were given at a median dose of 1×106 cells/kg once weekly until aGVHD got complete response (CR) or MSCs were infused for a total of 8 doses. Lymphocyte subsets of T-cell, B-cell, and NK-cell in peripheral blood were analyzed by flow cytometry before and 30, 60, 90, 180 and 360 days after the MSC infusion in MSC group and the corresponding period in the control group. Results A total of the 33 patients who survived more than 30 days after the study treatments were evaluated for the alterations in cellular immune compartment and cGVHD, including 15 cases in MSCs group and 18 in non-MSCs group. In MSCs group, patients had a significantly higher CD4+/CD8+ T-cell ratio at 60, 90 and 180 day after MSCs treatments, which subsequently equalized at 360 day compared with non-MSCs group. The MSC group presented higher percentages of CD4+CD25+ regulatory T cells (Treg) comparing with non-MSCs group, especially at 90 and 180 day, and approached at 360 day. The proportion of CD4+CD45RO+ and CD4+CD45RA+ naïve T-cells in MSC group were also higher than those in non-MSCs group at 60, 90 and 180 day, but not different at 360 day. The proportion of CD19+ and CD16+CD56+ was not detected striking difference between the two groups. Four patients (26.7%) experienced cGVHD in MSCs group, compared with twelve (66.7%) in non-MSCs group (p=0.02). Conclusions In conclusion, our data indicate that MSCs might ameliorate aGVHD and induce longer-lasting immune tolerance by altering cellular immune compartments in peripheral blood. The alteration of the cellular immune compartments is associated with the protecting and repairing role of MSCs to thymus.
