چکیده انگلیسی


- MSCs treated with pro-inflammatory cytokines do not show morphological changes.
- MSCs were CD45+ after exposure to the Th17 cell polarizing condition.
- Multilineage differentiation capacity of cytokine-treated MSCs increased.
- Immunomodulatory function of cytokine-treated MSCs is well maintained.
- Pro-inflammatory cytokine-treatment of MSCs enhances their efficacy in cell therapy.

Mesenchymal stem cells (MSCs), as cells with potential clinical utilities, have demonstrated preferential incorporation into inflammation sites. Immunophenotype and immunomodulatory functions of MSCs could alter by inflamed-microenvironments due to the local pro-inflammatory cytokine milieu. A major cellular mediator with specific function in promoting inflammation and pathogenicity of autoimmunity are IL-17-producing T helper 17 (Th17) cells that polarize in inflamed sites in the presence of pro-inflammatory cytokines such as Interleukin-1β (IL-1β), IL-6 and IL-23. Since MSCs are promising candidate for cell-based therapeutic strategies in inflammatory and autoimmune diseases, Th17 cell polarizing factors may alter MSCs phenotype and function. In this study, human bone-marrow-derived MSCs (BM-MSC) and adipose tissue-derived MSCs (AD-MSC) were cultured with or without IL-1β, IL-6 and IL-23 as pro-inflammatory cytokines. The surface markers and their differentiation capacity were measured in cytokine-untreated and cytokine-treated MSCs. MSCs-mediated immunomodulation was analyzed by their regulatory effects on mixed lymphocyte reaction (MLR) and the level of IL-10, TGF-β, IL-4, IFN-γ and TNF-α production as immunomodulatory cytokines. Pro-inflammatory cytokines showed no effect on MSCs morphology, immunophenotype and co-stimulatory molecules except up-regulation of CD45. Adipogenic and osteogenic differentiation capacity increased in CD45+ MSCs. Moreover, cytokine-treated MSCs preserved the suppressive ability of allogeneic T cell proliferation and produced higher level of TGF-β and lower level of IL-4. We concluded pro-inflammatory cytokines up-regulate the efficacy of MSCs in cell-based therapy of degenerative, inflammatory and autoimmune disorders.
