一細胞質量分析研究チーム
[2021年3月 終了]
生命の構成単位である細胞は、様々な刺激に対して様々な応答を示します。こうした変化を経時的、網羅的かつ定量的に評価し、細胞のダイナミクスを明らかにすることで、外界の変化に対する生命の応答、発生の分子機構、細胞の癌化のメカニズムなど、生命の様々な側面を理解するのに役立ちます。一細胞質量分析研究チームでは、ナノスプレーチップを用いた一細胞質量分析技術およびキャピラリー電気泳動質量分析技術を併用することによって細胞内の代謝物やタンパク質などの分子群の網羅的変化を、一細胞レベルで明らかにする技術を開発し、構築した要素技術を1細胞創薬や診断新技法の開発へと展開させていくことを目指しています。
研究テーマ
- 一細胞質量分析法の開発
- 超高感度キャピラリー電気泳動質量分析法の開発
- 一細胞創薬・一細胞診断技術の開発
