Outline of Final Research Achievements |
The tongue frenum is crucial structure, since it is involved in pronunciation and formation of dentition. Aberrant tongue frenum induce several diseases including ankyloglossia. However, it remains unclear how tongue frenum is formed. Understanding molecular level of tongue frenum formation is important for elucidating mechanisms of tongue frenum formation. Cells in most anterior part of Lgr5/Tbx22/Osr2 expressing region were found to migrate along lingual-buccal axis to form the tongue frenum. Disruption of the cell migration resulted in aberrant tongue frenum.

Academic Significance and Societal Importance of the Research Achievements |
歯列、発音、口腔清掃は、舌小帯の形態に大きな影響を受ける。舌小帯が高位であったり、短い場合には、発音障害や歯列不正など様々な問題を引き起こす。舌小帯の治療後に、発音障害、歯列不正が残存した場合、その処置には長い時間を要することがある。将来、異常な舌小帯を予測し、早期に対処することが望ましいが、舌小帯の形成メカニズムは全く明らかとなっていない。分子レベルでの本研究成果は、今まで分子生物学的知見がほとんどなかった舌小帯に新たな展開をもたらし、舌小帯異常の新たな治療法や再生療法の基盤的知見となる。
