Objective To observe influence of fibrin sealant(FS) on osteoinductive ability of inject type BMP.Method The inject type BMP power was dissolved in the main glue part or thrombin part of FS, then mixed with the main glue part or thrombin part of FS into gel, observe coagulating time, then implant composite into the thigh muscle pouch of mice to evaluate their capacity to induce new bone formation, and compared to the single BMP implant group.Result There was no difference in the coagulating time between two mixing method, the osteoinductive ability of implants BMP dissolved in the main glue part or thrombin part of FS group was higher than that of simply BMP implant group.Conclusion FS was perfect carrier to inject type BMP.
