最近的研究发现,间充质干细胞(MSCs)凭借其组织修复和免疫调节特性,在各种自身免疫性疾病和退行性疾病中显示出广阔的应用前景。尽管MSCs的潜在治疗用途是可观的,但由于MSCs的异质性,研究和临床治疗效果尚处于初步阶段。在此,基于RNA测序(RNA-seq)和单细胞序列特性,我们证明了B7-H1在依赖STAT3信号的胶原性关节炎小鼠模型中,在人牙龈间充质干细胞(GMSCs)的免疫抑制功能中发挥着重要作用。我们的数据提供了令人信服的证据,表明GMSCs表达B7-H1有助于识别具有更强免疫抑制特性的新的MSCs亚群。该方法为以干细胞为基础的自身免疫性疾病和其他炎症性疾病的治疗提供了一种独特的额外策略。由于间充质干细胞的异质性,其临床治疗效果尚处于初步阶段。Wu等人。研究表明,B7-H1的表达有助于识别具有更强免疫抑制特性的新的MSC亚群。该方法为以干细胞为基础的自身免疫性疾病的治疗提供了一种独特的额外策略。
Recent studies found that mesenchymal stem cells (MSCs), by virtue of their tissue recovery and immunoregulatory properties, have shown a broad prospect for applications in various autoimmune and degenerative diseases. Although the potential therapeutic use of MSCs is considerable, studies and clinical treatment efficacy are preliminary due to the heterogeneity of MSCs. Herein, based on RNA-sequencing (RNA-seq) and single cell sequence properties, we demonstrated that B7-H1 plays an important role in the immunosuppressive function of human gingiva-derived mesenchymal stem cells (GMSCs) in a collagen-induced arthritis murine model that is dependent on STAT3 signaling. Our data offer convincing evidence that B7-H1 expression by GMSCs helps to identify a new subpopulation of MSCs with a greater immunosuppressive property. The approach provides a unique and additional strategy for stem cells-based therapies of autoimmune and other inflammatory diseases. The clinical treatment efficacy of mesenchymal stem cells (MSCs) is preliminary due to the heterogeneity. Wu et al. showed that B7-H1 expression helps to identify a new subpopulation of MSC with a greater immunosuppressive property. The approach provides a unique and additional strategy for stem cells-based therapies of autoimmune diseases.
