摘要:

文题释义:

组织工程:为综合运用支架材料、种子细胞和生物分子,通过在体外人工构建组织或器官并在体内移植以改善、替代和再生损伤或患病的组织和器官。然而,由于目前该过程产生的组织范围有限,为了扩展其在人类的临床应用,在该领域中还需要很多研究推进。

膝关节半月板:是一种月牙状纤维软骨,充填在股骨与胫骨关节间隙内,每个膝关节有2个半月板:内侧半月板与外侧半月板。它们的周围部分较厚,附着于胫骨平台的边缘而中央部分则较薄,其接触股骨髁的上面略凹陷而接触胫骨髁的下面则平坦,膝关节半月板中内分无血液供应区,其营养主要来自滑液,只有与胫骨缘连接的边缘部分能从滑膜得到血液供应。

背景:半月板软骨损伤是膝关节最常见的损伤之一。在过去的10年中,基于干细胞的治疗方法得到了广泛的应用,有关这一课题的研究数量迅速增加。最近的几项研究表明多潜能干细胞存在于半月板内,有可能在半月板愈合中发挥关键作用。

目的:确定半月板组织工程相关的干细胞来源和培养条件,了解组织工程半月板目前发展现状。

方法:通过PubMed、Embase、EBSCO、Cochrane library、Clinical library数据库进行在线文献检索,检索时间范围为2009至2019年。纳入与半月板组织工程和种子细胞选择有关的文章,最终对64篇文献进行综述。

结果与结论:干细胞因其强增殖能力和全能性而被作为种子细胞广泛应用于组织工程半月板研究,且能很好地修复动物半月板损伤,目前还无法确定在临床上有同样的效果,因此离临床应用还有一定距离。

Abstract:

BACKGROUND: Meniscus cartilage injury is a most common injury of knee joint. In the past decade, stem cell based therapies have been widely applied, and the related studies have been increased rapidly. Pluripotent stem cells have been shown to exist in the meniscus, which may play a key role in the healing of meniscus.

OBJECTIVE: To determine the source and culture conditions of stem cells related to tissue-engineered meniscus, and to understand the current development status of tissue- engineered meniscus.

METHODS: PubMed, Embase, EBSCO, Cochrane library, and Clinical library databases were retrieved for relevant articles published between 2009 and 2019. The articles concerning tissue-engineered meniscus and selection of seed cells were selected, and finally 64 eligible articles were included for analysis.

RESULTS AND CONCLUSION: Stem cells have been extensively used as seed cells in tissue-engineered meniscus due to its high proliferation ability and multipotent property. These cells can effectively repair the meniscus in animals, but the clinical outcomes still remain unclear. Therefore, there is a certain distance from basic research to clinical application.

Key words: stem cells, meniscus repair, regeneration, tissue engineering, influencing factors
