摘要:

文题释义:

半月板:是位于膝关节胫骨平台与股骨内外髁之间的新月型纤维软骨组织,形态上呈“内CO”,起到了承载负荷、吸收震荡以及稳定关节的重要作用,其损伤或切除容易造成膝关节软骨磨损从而引发早期骨关节炎。

脱细胞支架:由经化学和物理的方法去除异体或异种组织中的细胞,形成无免疫原性或低免疫原性的材料构建的组织工程支架。

背景:半月板作为膝关节的重要解剖结构,损伤或者手术切除等均有可能导致早期骨关节炎。因此,利用组织工程技术寻求一种可完全模仿正常生理半月板的取代物尤为重要。

目的:总结近年来半月板组织工程的种子细胞、支架、刺激物的研究进展。

方法:检索PubMed数据库、Web of scienceCNKI中国期刊全文数据库、万方数据库收录的文献。英文检索词为:“meniscustissue engineeringmesenchymal stem cellscaffoldSynthetic polymer scaffoldspolycaprolactonehydrogelECM component scaffoldtissuesmall intestine submucosadecellularizedgrowth factordynamic compressiontensilecyclic hydrostatic pressure”,中文检索词包括:“半月板、组织工程、干细胞、支架、人工聚合物支架、水凝胶、细胞外基质组分支架、小肠黏膜下层、脱细胞技术、生长因子、动态压缩试验、抗拉伸负荷、循环静水压试验”,最终纳入61篇文献进行总结。

结果与结论:种子细胞、支架以及生物与物理刺激物是组成半月板组织工程的重要三元素。间充质干细胞仍然是当今组织工程中最为常用的种子细胞,其可种植于人工聚合物支架或者天然支架如细胞外基质组分支架与组织衍生支架,也可通过水凝胶包裹,在体内外生长因子与力学刺激作用下,进而形成再生半月板。现如今半月板组织工程更倾向于系统性综合种子细胞、支架、刺激物成一个体系来研究。因此,如何探索出一套最符合半月板解剖结构、生理功能以及生物相容性的组织工程体系已成为目前组织工程的研究热点。

Abstract:

BACKGROUND: As a necessary anatomic structure of knee joint, meniscus injury or meniscectomy could possibly contribute to the initiation of early osteoarthritis. Therefore, it is very important to use tissue engineering technology to find a substitute that can completely imitate normal physiological meniscus.

OBJECTIVE: To summarize the research progress of cell, scaffold and stimulus of meniscus tissue engineering.

METHODS: The authors searched PubMed, Web of science, CNKI and Wanfang database to discover eligible articles. The key words were “meniscus; tissue engineering; mesenchymal stem cell; scaffold; synthetic polymer scaffolds; polycaprolactone; hydrogel; ECM component scaffold; tissue; small intestine submucosa; decellularized; growth factor; dynamic compression; tensile; cyclic hydrostatic pressure” in English; and “meniscus, tissue engineering, stem cells, scaffolds, artificial polymer scaffolds, hydrogel, extracellular matrix scaffolds, small intestinal submucosa, acellular technology, growth factors, dynamic compression test, tensile load, and cyclic hydrostatic pressure test” in Chinese. Finally, 61 articles were included.

RESULTS AND CONCLUSION: Seed cell, scaffold and biological and physical stimulus are three significant important factors in meniscus tissue engineering. Mesenchymal stem cell is so far the most commonly applied seed cell in tissue engineering. Stem cells can be implanted on synthetic polymer scaffold or nature scaffold like extracellular matrix component scaffold and tissue-derived scaffold, or wrapped by hydrogel. With the endogenous or exogenous growth factors and biomechanical stimulation, meniscus regeneration will proceed. Nowadays, researchers tend to systematically integrate seed cell, scaffold and stimulus into a system to study. Therefore, the construction of a system which mostly fits the anatomic structure, physiologic function and biocompatibility of meniscus has become a current hotspot in tissue engineering.
