近日,受国际著名杂志Cell Press的Trends in Immunology杂志邀请,中国科学院上海生命科学研究院/上海交通大学医学院健康科学研究所时玉舫研究员领导的免疫与组织干细胞研究组于2012年1月在线发表了题为“How mesenchymal stem cells interact with tissue immune responses”的研究综述文章。
该综述基于近年来时玉舫研究组对于间充质干细胞免疫学的主要研究成果和该领域的最新进展,系统阐述了间充质干细胞与免疫系统的相互作用及其机制,疾病发生过程中的作用,并对创伤愈合的影响以及其在临床应用中的广阔前景,提出了此领域内亟需解答的关键问题。
间充质干细胞(mesenchymal stem cells,MSCs)是骨髓中除造血干细胞以外的一种组织干细胞,广泛分布于骨髓、肝脏、脂肪、脐带等多种组织中,具有强大的自我更新能力和多向分化潜能。因此,间充质干细胞移植在再生医学领域具有广阔的应用前景。同时,作为一种重要的免疫调节细胞,MSCs在炎症细胞因子刺激后对免疫系统表现出很强的调节作用,所以MSCs有望应用于治疗系统性红斑狼疮等自身免疫疾病。在时玉舫研究员的带领下,该研究组科研人员对间充质干细胞与免疫系统的相互作用进行了系统的研究工作,阐明了间充质干细胞对于免疫系统具体的调节机制,极大地丰富了人们对于间充质干细胞的理解,在该研究领域成果显著,受到了国际同行的广泛关注。(生物谷Bioon.com)

How mesenchymal stem cells interact with tissue immune responses
Yufang Shi, Juanjuan Su, Arthur I. Roberts, Peishun Shou, Arnold B. Rabson, Guangwen Ren
Mesenchymal stem cells (MSCs), also called multipotent mesenchymal stromal cells, exist in almost all tissues and are a key cell source for tissue repair and regeneration. Under pathological conditions, such as tissue injury, these cells are mobilized towards the site of damage. Tissue damage is usually accompanied by proinflammatory factors, produced by both innate and adaptive immune responses, to which MSCs are known to respond. Indeed, recent studies have shown that there are bidirectional interactions between MSCs and inflammatory cells, which determine the outcome of MSC-mediated tissue repair processes. Although many details of these interactions remain to be elucidated, we provide here a synthesis of the current status of this newly emerging and rapidly advancing field.
