Outline of Research at the Start

超高齢社会日本において、生体内にインプラントを留置する手術は増加している。感染・ゆるみ等の合併症を回避し、長期間高機能を保つインプラントが求められており、インプラント周囲に適切な炎症と線維化を誘導する必要がある。
本研究では、従来の動物モデルを用いた実験の枠組みを超えた種間差に配慮して、異物反応および異物巨細胞の分化メカニズムおよび機能を明らかにする。本研究の成果によって、生物学的理解に立脚したインプラントが開発されると期待される。

Outline of Final Research Achievements

In aged society Japan, surgeries transplanting implants are increasing. In surgeries with implants, infection and loosening should be avoided. In addition, implants are expected to work functionally for longer time than recent ones. Authors has an idea good balance between inflammation and fibrosis is necessary for long-lasting durable implants. Foreign body giant cells (FBGCs) exist around transplanted implants, however, their function and differentiation pathway were not well known. FBGCs might be key for foreign body reaction.
Authors performed single cell analysis for through transcriptomic information around cell reaction around implants. Furthermore, authors tried to check single nucleus heterogeneity inside giant cells including osteoclasts, whose origin is the same as FBGCs. Finally, authors established living subcellular sequencing to investigate transcriptomic heterogeneity.

Academic Significance and Societal Importance of the Research Achievements

超高齢社会日本では、生体内にインプラントを留置する手術が増加し続けている。感染・ゆるみ等の合併症を回避し、長期間高機能を保つインプラントが求められる。インプラントが適切に機能を発揮するためには、物理的安定性だけでは不十分であり、生物学的因子が程よく調整される必要がある。申請者は、インプラント周囲に適切な炎症と線維化を誘導できれば、インプラントのさらなる長寿命化が可能であると考えている。異物周囲に存在することが分かっている異物巨細胞の起源および機能解析から、長寿命化のヒントを得る。本研究成果は、超高齢社会日本が抱える課題解決に有用であると考えている。
