Abstract:
BACKGROUND:As meniscectomy may result in various adverse reactions, tissue-engineered meniscus is expected to be used for meniscus repair. Seed cel selection and optimal physicochemical stimuli are crucial for the construction of tissue-engineered meniscus.
OBJECTIVE:To overview the seed cel s for the tissue-engineered meniscus construction and the research progress of physicochemical factors.
METHODS:The first author retrieved the CNKI and Medline databases using the keywords of“meniscus, tissue engineering, seed cel s, physical and chemical factors”in English and Chinese, respectively, to retrieve articles related to the seed cel s and physicochemical factors of the tissue-engineered meniscus construction. Irrelative and repetitive articles were excluded, and 49 eligible articles were enrol ed for analysis.
RESULTS AND CONCLUSION:The seed cel s must maintain their phenotype and synthetic ability after physicochemical stimulation in combination with scaffolds, to achieve the reproducibility of tissue-engineered meniscus. Most of cytokines can be used for promoting the proliferation and differentiation of chondrocytes, but the underlying mechanisms were little known. Their application in the meniscus tissue engineering needs to be studied in depth. Currently it is urgent to improve physicochemical stimuli in order to construct the tissue-engineered meniscus. The shear force does harm to chondrocyte phenotype, and dynamic compression loading has been proved to enhance Ca+and glycosaminoglycan release. The fibrous cartilage stimulated by shear force and other factors may be helpful for constructing the tissue-engineered meniscus. An elaborated randomized control ed trial and the long-term quantitative analysis are of importance to assess the research results.
