Outline of Final Research Achievements |
Previous evidence suggested that tissue-fibrinolytic system and subsequent proteolytic system and growth factor induction play important roles in tissue repair. We therefore investigated the roles of tissue-fibrinolytic system in bone repair and regeneration in this study. We established the model to evaluate the process of bone repair and regeneration by making a bone defect in mouse femorae. We demonstrated that plasminogen is crucial for bone repair process using plasminogen-deficient mice. Moreover, tissue-type plasminogen activator (tPA) is involved in bone repair using tPA-deficient mice. In that study, we showed that tPA enhances the proliferation of osteoblasts through Annexin 2 and MAP kinase.
