Mesenchymal stem cells (MSCs) represent a heterogeneous population of stromal cells with pluripotent mesenchymal differentiation potential. They have been found to have immunosuppressive properties and the ability to modulate angiogenesis and endogenous tissue repair by in vitro and animal studies. Clinical trials have examined the utility of these cells in autoimmune and inflammatory conditions. In particular, in allogeneic hematopoietic stem cell transplant (HSCT), multiple studies have been conducted to explore the use of MSC to treat acute and chronic graft-versus-host disease (GVHD) and for cotransplantation with HSCT to promote HSC engraftment and prevent GVHD. We review here the results of these studies and discuss some challenges of this treatment modality in this disease setting.
间充质干细胞(MSCs)是具有多能间充质分化潜能的异质性基质细胞群体。体外研究和动物研究发现,它们具有免疫抑制特性以及调节血管生成和内源性组织修复的能力。临床试验已对这些细胞在自身免疫性疾病和炎症性疾病中的效用进行了研究。特别是在异基因造血干细胞移植(HSCT)中,已经开展了多项研究来探索使用间充质干细胞治疗急性和慢性移植物抗宿主病(GVHD),以及与造血干细胞移植联合移植以促进造血干细胞植入并预防移植物抗宿主病。我们在此回顾这些研究结果,并讨论这种治疗方式在该疾病背景下所面临的一些挑战。
