摘要:

 背景:关节软骨缺损自我修复能力有限,传统手段难以修复,关节软骨组织工程为修复大面积关节软骨缺损提供了崭新的方法和途径。

目的:综述组织工程技术修复关节软骨的现状、问题及前景。
方法:检索PubMed数据库1982至2015相关文献,以“Articular cartilage,repair,tissue engineering”为检索词进行检索。纳入与关节软骨组织工程修复相关的文献,排除重复性研究。根据纳入标准,排除无关联或重复的文献,最终保留39篇文献进行综述。
结果与结论:优良的种子细胞具有软骨细胞分化潜能,目前用于关节软骨修复的种子细胞主要有间充质干细胞、胚胎干细胞、脂肪源干细胞及前软骨干细胞等4大类。生长因子趋向于联合应用,生长因子具有诱导宿主实质细胞在体内生长,提高种植的细胞稳定性,加快组织再生的作用。复合支架材料有利于促进细胞接种和细胞的空间分布,促进细胞增殖,是研究的热点。如何优化种子细胞、支架材料和细胞因子的选择和匹配,建立新型复合模式,以获得最佳的关节软骨修复效果,是未来的重要发展方向。

Abstract:

BACKGROUND: Articular cartilage has limited ability to repair itself, and the traditional means are difficult to repair articular cartilage defects, but articular cartilage tissue engineering provides new methods and approaches for large-area articular cartilage defects.

OBJECTIVE: To review the current status, problems and prospects of tissue engineering technology in articular cartilage repair.
METHODS: The retrieval of PubMed database was performed for articles published from 1982 to 2015, with the keywords of “articular cartilage, repair, tissue engineering” in English. Literatures related to tissue engineering repair of articular cartilage were included, but repetitive studies were excluded. Finally 39 articles were reserved in result analysis.
RESULTS AND CONCLUSION: Excellent seed cells have chondrogenic differentiation potential, and currently, the main seed cells for articular cartilage repair include mesenchymal stem cells, embryonic stem cells, adipose-derived stem cells and precartilaginous stem cells. Different growth factors, which can induce the in vivo growth of host parenchymal cells, improve seeded cell stability, and accelerate tissue regeneration, tend to be combined in clinical application. Composite scaffolds are also one of hot researches that can promote cell  inoculation and spatial distribution as well as accelerate cell proliferation. To obtain the best effectiveness of articular cartilage repair, how to optimize seed cells, select and match scaffold materials to construct new types of composite patterns is an important direction in the future.
