Outline of Final Research Achievements |
It is becoming clear that lactate plays an important role in tissue regeneration and hard tissue differentiation. We found that lactate deficiency in a low glucose environment inhibits hard tissue formation in periodontal ligament cells and that lactate may be an energy source that promotes periodontal tissue regeneration. In this study, using human periodontal ligament cells, we elucidated part of the mechanism by which lactate, as a “bioactive substance,” is useful for periodontal tissue regeneration. Furthermore, based on the results obtained in this study, we will establish a basis for developing a novel periodontal tissue regeneration therapy using lactic acid agents.

Academic Significance and Societal Importance of the Research Achievements |
本研究においては, 細胞分化に必要なエネルギー源を供給する「生理活性物質」として乳酸を歯周組織再生治療に応用できる可能性を探るという点であり, 乳酸が組織再生を活性化させる因子として利用するというアイデアの点で学術的意義がある。また現在, 歯周組織再生治療に用いる薬剤や材料はその製造には高価なコストがかかるというデメリットがある。しかし, 乳酸製剤はトウモロコシやイモ等の植物から作ることが可能であるため製造コストは非常に安価であり, アレルギーなどの有害事象についても少ないという特色に社会的意義を見出すことができると考える。
