组织工程半月板研究进展

RESEARCH PROGRESS IN TISSUE ENGINEERED MENISCUS

目的对使用组织工程技术构建半月板的研究进展及其应用情况进行综述。方法广泛查阅近年来通过组织工程构建半月板的相关文献,分别从种子细胞、支架材料及生物反应器3个方面进行分析总结。结果组织工程半月板越来越受到人们的重视,近年来对种子细胞、支架材料及生物反应器的研究均取得了可喜进展,但研究成果真正应用于临床尚需努力。结论寻求更加有效的构建方法仍然是组织工程半月板的研究热点,随着对种子细胞、支架材料及生物反应器认识的不断深入,必将会构建出更接近于人体的组织工程半月板。

Objective To elucidate the latest research progress and application of tissue engineered meniscus. Methods The literature concerning the advance in tissue engineered meniscus was extensively reviewed, then closely- related issues including seed cells, scaffolds, and bioreactors were analyzed. Results With more and more attention being paid to meniscus tissue engineering, different approaches and strategies for seed cells, scaffolds, and bioreactors have contributed to the generation of meniscal constructs, which are capable of restoring meniscal lesions to some extent, but translating successes in basic science research to clinical application is still limited. Conclusion More research for the optimal combination of the appropriate cell source, the scaffold type, and the proper physical and chemical factors for the stimulation of cells differentiation into tissue with optimal phenotypes in tissue engineered meniscus is still in needed, but the overall future looks promising.
