Outline of Research at the Start

個体老化の顕著な表現型は,骨格筋機能低下に伴う運動,代謝機能の棄損である.これら加齢に伴う骨格筋機能の低下は加齢性筋萎縮(サルコペニア)と定義され,死亡率との高い相関性から積極的な介入研究の必要性が示されてきた.従来の研究ではサルコペニアは,成体骨格筋に存在する骨格筋幹細胞の数が激減することで骨格筋の再生が困難となることが示唆されてきた.一方で,増殖せずに組織内で保持されているはずの幹細胞数が老化に伴い減少するメカニズムについて未だ不明な点が多い.本研究では,個体老化に伴う組織全体の骨格筋幹細胞数の減少を幹細胞ニッチの機能破綻に着目し,老化細胞の形成と伝播の観点から解明を試みる.

Outline of Final Research Achievements

In this study, we aimed that elucidating the mechanism by which senescent cells accumulate in tissues and cause functional decline by altering surrounding cells. First, we developed a single-cell spatial proteomics technology based on immunostaining to analyze age-related cellular state changes and their spatial distribution. Next, we used this spatial proteomics approach to analyze mouse skeletal muscle tissues ranging from young to aged specimens. The results revealed a dramatic decrease in specific epigenomic states across all cell types, beginning at relatively young ages. Furthermore, experiments with cultured cells showed that inhibiting these epigenomic factors induced cellular senescence, suggesting that the loss of specific epigenomic information influences aging.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的・社会的意義は、老化メカニズムの根本的理解を深めた点にある。免疫染色を基盤とした1細胞空間プロテオーム技術の開発は、加齢に伴う細胞変化を空間的文脈で解析することを可能とした。この手法を用いて、比較的若齢機からのエピゲノム状態変化の発見は、加齢の初期段階の理解に貢献する。さらに、特定のエピゲノム情報と細胞老化の因果関係を実証したことで、加齢関連疾患の予防、治療への新しい介入標的を提示した。これらの知見は高齢化社会における健康寿命延伸に向けた基盤的知識となりうる。
