BACKGROUND: The previous methods for the repair of tendon defect include end-to-end method, autologous tendon graft, tendon al ograft or artificial tendon transplantation, but each method has its advantages and disadvantages. OBJECTIVE: To investigate the feasibility of constructing tissue-engineered tendon by rabbit bone marrow mesenchymal stem cells as seed cells which were induced by bone morphogenetic protein 12 and with col agen-polyglycolic acid composite as frameworks in the repair of rabbit tendon defects. METHODS: Bone marrow was separated from rabbit proximal femur to harvest cells, and the cells were passaged to the second generation and induced with 10 μg/L bone morphogenetic protein 12. Then the passage 2 cells were implanted into the prefabricated tissue-engineered tendon on the polyglycolic acid stitch with certain percentage together with col agenⅠsolution. The rabbits were used to establish the Achil es tendon defect models, and different methods were used to repair Achil es tendon defect: tissue-engineered tendon, col agenⅠ-polyglycolic acid stitch and end-to-end suturing in silk. Morphology, mechanics and shistopathology of the tissue-engineered tendon were observed. RESULTS AND CONCLUSION: Pathomorphological observation of histological section after 12 weeks showed that multiple fusiform fibroblasts were homogeneously distributed in col agen in the direction of stress mechanics.Fibrocytes increased obviously, new smal vessels could be seen and col agen was found aligned compactedly. In col agen Ⅰ-polyglycolic acid stitch group, a part of fibroplasia hyperplasia accompanied by granulation tissue formation could be seen, the col age fibers were in loose filamentous network and the cells were distributed disorderly and unevenly. Granulation tissue formed around the fibrous tissue in the silk group. Biomechanics strength in bone morphogenetic protein 12+polyglycolic acid group was better than that in the col agen Ⅰ-polyglycolic acid group, and there was significant difference when compared with suture silk group. The biomechanics strength of the bone morphogenetic protein 12+polyglycolic acid group was lower than that of normal tendon. It is possible to construct a tissue-engineered tendon with autologous bone marrow mesenchymal stem cells as seed cells induced by bone morphogenetic protein 12 and with the col agen-polyglycolic acid as the framework. Constructed tissue-engineered tendon has biomechanics characteristics and can be used to repair Achil es tendon defect.
