Outline of Final Research Achievements

We morphologically analyzed the healing process of the extraction socket, focusing on the dynamics of macrophages. Bone formation in the extraction socket suggests that CD206-positive M2-like macrophages produced TGF-b1 and promoted osteoblastic differentiation. In addition, when tooth extraction was performed after depletion of macrophages by clodronate-liposome administration, bone formation was suppressed. These results indicate that tissue-repairing M2-like macrophages and their cytokine production play an important role in the healing process of tooth extraction sockets.

Academic Significance and Societal Importance of the Research Achievements

抜歯窩治癒過程における組織修復型M2マクロファージの役割についてはほとんど注目されていなかった。本研究により、マクロファージは細菌や死細胞の処理のみならず、組織修復に関連するサイトカインを誘導し、骨原性細胞を増殖・分化させることにより抜歯窩治癒を促進することを明らかにできた。また、マクロファージ由来骨再生因子が歯周病治療やインプラント治療に応用できる可能性を示唆できたことは社会的意義が高い。
