A summary of the article is shown below:
Sulfur mustard (SM) exposure, whose symptoms are similar to radiation exposure, can lead to acute injury. Because mesenchymal stromal cells (MSCs) have been used to experimentally and clinically treat acute radiation syndrome, in this study, MSCs were intravenously injected into rats after percutaneous SM exposure. Then, we examined sternum and spleen samples by histopathological and immunohistochemical methods to observe pathological changes. Furthermore, blood samples were taken to test the white blood cell count (W.B.C.), blood platelet count (B.P.C.) and red blood cell count (R.B.C.) and the levels of cytokines in the serum. The number of bone marrow karyocytes and the W.B.C. in the MSC + SM group were higher than those in the SM group, and the levels of G-CSF, GM-CSF, MCP-1, IL-1α, IL-5 and IFN-γ in the MSC + SM group remained high at different time points after SM exposure. In addition, the B.P.C., the level of EPO and the relative weight of the spleen in the MSC + SM group were significantly higher than those in the SM group. Meanwhile, spleens in the MSC + SM group were more hyperplastic and hematopoietic, and had fewer apoptotic cells than in the SM group. Furthermore, rat body weight and locomotion ability in the MSC + SM group were higher than in the SM group. This evidence supports the potential ability of MSCs in immunoregulation and functional improvements to the hemopoietic microenvironment. Intravenous injection of MSCs exerted significant therapeutic effects in rats with percutaneous exposure to SM.
