Abstract:

BACKGROUND: The effect of autologous or allogeneic transplantation in the repair of damaged meniscus is not ideal, so the application of tissue engineering technology in meniscus reconstruction has become the research focus.
OBJECTIVE: To investigate the feasibility of tissue engineering technology for repair and reconstruct damaged meniscus.
METHODS: The seed cells used for in vitro construction of tissue engineering meniscus were cultured, and the meniscal scaffold materials were prepared, then the seed cells were attached on the scaffold materials, and the cytokine was used to regulate the adhesion, growth, differentiation and migration of seed cells. Histological examination was performed to observe the binding between cells and scaffolds, as well as the number of the cells.
RESULTS AND CONCLUSION: The research of tissue-engineered meniscal repair included seed cells, scaffold materials and cytokines. The seed cells were constructed, including bone marrow mesenchymal stem cells and meniscal fibrocartilage cells, and the best effect concentration could be obtained after the meniscal fibrocartilage cells passaged to the third generation. Surface modification of tissue-engineered meniscus scaffold materials was performed, and the multi-material composed composite materials have better biocompatibility. The repair and construction of damaged meniscus with tissue engineering technology is the new treatment mode for repair of meniscus damage.
