live cell response to mechanical stimulation studied by integrated optical and atomic force microscopy

高い空間分解能と時間分解能を持つサブ細胞レベルでの細胞の挙動を調査することができる新技術、生きている細胞は機械的な力を感知するメカニズムを理解するために、およびそれらがどのように対応し、その環境に適応することは開発されました。このように、原子間力顕微鏡（AFM）は、全内部反射蛍光（全反射）顕微鏡と高速回転ディスク（FSD）共焦点顕微鏡と統合されました。統合されたシステムは、リアルタイムでの機械的刺激への細胞応答の直接光イメージングを可能にする、任意の付着生細胞における分子動力学研究の広い範囲にわたって広く適用可能である。アクチンフィラメントと接着斑の大幅な再編成が原因で、細胞体全体の細胞構造に変化を誘導することが頂端細胞の表面での局所力学刺激することが示された。これらの革新的な技術は、機械的な力に反応して生細胞の再構築とダイナミクスを理解するための新たな情報を提供します。機械的な刺激にショーの生細胞応答が記載されている詳細なプロトコールと代表的なデータセット。
