Abstract Background: Mesenchymal stem cells (MSCs) shows significant therapeutic effects in type 1 diabetes mellitus (T1DM) as they could regulate the inflammatory processes. However, little is known about the process of MSCs immunosuppression in T1DM. In this study, we investigated the effects of wild type p53-induce phosphatase 1 (Wip1) on regulating MSCs immunosuppressive capacities in T1DM mice.Methods: Primary wild type (Wip1+/+) MSCs and Wip1 knockout (Wip1−/−) MSCs were cultured in vitro. T1DM mouse model was induced with streptozotocin and then was treated with Wip1+/+ MSCs (5 × 105) or Wip1−/− MSCs (5 × 105) by tail vein injection. The general physiological states of T1DM mice were measured every week. Moreover, the pathological changes in the pancreatic tissue were observed. Enzyme-linked immunosorbent assay (ELISA) and flow cytometry were used to detect the expressions of inflammatory cytokines in mice.Results: Wip1 −/− MSCs had lower therapeutic effects in T1DM mice. Moreover, we screened and confirmed bone marrow stromal cell antigen2 (BST2) gene that showed the target gene for Wip1 through gene chips, quantitative polymerase chain reaction and Western blot. Wip1−/− MSCs exhibited lower immunosuppressive capacity, as evidenced by enhanced expression of BST2, with concurrent increased expression of interferon-α (IFN-α). In vivo distribution analysis results indicated that Wip1−/− MSCs homed to the damaged pancreatic tissue. Wip1−/− MSCs influenced the expression of immune factors by remarkably increasing the expression of tumor necrosis factor-α (TNF-α), interleukin-17A (IL-17A), IFN-α, IFN-β, and IFN-γ and decreasing the expression of IL-4 and IL-10.Conclusions: Wip1 affects MSCs immunomodulation by regulating the expression of IFN-α/BST2. These findings suggest that Wip1 is required to regulate the therapeutic effects of MSCs on T1DM treatment, indicating a novel role of Wip1 in immunoregulation.

Type 1 diabetes mellitus is characterized by the destruction of pancreatic β-cells and requires the regeneration of these destroyed pancreatic β-cells for radical treatment. The degeneration of organelles in stem cells compromises stem cell quality; however, organelles in the mesenchymal stem cells of patients with type 1 diabetes mellitus have not been characterized previously. In this study, we use transmission electron microscopy to evaluate the degeneration of organelles in adipose-derived stem cells of patients with type 1 diabetes mellitus (T1DM ADSCs). Compared to adipose-derived stem cells from healthy humans, T1DM ADSCs degenerate differently, characterized by prominent enlarged spherical vesicles. The exosomes of T1DM ADSCs are found to be enlarged, reduced in number, and increased in the percentage of those positive for tetraspanin CD9. The findings of this study provide insight into the characteristics of stem cells in patients with type 1 diabetes mellitus.
