Outline of Research at the Start

本研究では、膵癌治療および患者予後に決定的な影響を及ぼす転移に焦点を絞り、ヒトプライマリ膵癌オルガノイドを用いた人為的な癌間質の操作とその特性解析、独自のシングルセルレベルでの解析手法(Sekine K et al, Nature 2017)を応用し、in vitro転移モデルの作製、およびシングルセルおよび空間的トランスクリプトーム解析により転移メカニズムを明らかにし、転移を標的とした創薬開発システムの構築と転移制御を試みる。

Outline of Final Research Achievements

To establish a metastatic cancer model, we developed a co-culture system by mixing cancer cells and hepatocytes at various ratios and optimized the culture conditions. Medium composition, matrix type, and culture vessel were systematically adjusted, and temporal changes were monitored. In vivo, we constructed metastatic models using murine pancreatic cancer cells and human pancreatic cancer organoids, identifying several clones with metastatic potential. Evaluation using these models revealed that the pathological state of the target organ contributes to the promotion of metastasis. Furthermore, spatial transcriptomic and proteomic analyses identified associated molecules, and functional studies in vitro, as well as histological evaluations in vivo, were conducted.

Academic Significance and Societal Importance of the Research Achievements

本研究は、がん転移の病態を再現する高度なin vitroおよびin vivoモデルを構築することで、転移先臓器の状態が転移の促進に関与する可能性を示すことに成功した。これにより、個々の臓器環境に応じた転移機構の解明や、個別化医療の実現に向けた新たな知見が得られることが期待される。また、転移先のがん微小環境における立体的相互作用の理解が進むことで、今後の創薬や予後予測技術の発展への貢献も期待される。今後本技術を発展させることで、生体に近い転移評価系として、治療法の探索や薬剤反応性の予測精度向上にもつながる可能性が期待される。
