| Outline of Final Research Achievements |
The experimental method of measuring cell traction force (the force of cells to pull extracellular matrix and another cells) is called traction force microscopy (TFM). The dynamic mechanical behavior of cell-ECM and cell-cell interactions is known to influence a vast range of cellular functions, including necrosis, differentiation, adhesion, migration, locomotion, and growth. TFM can clarify the unique functions and properties of cells, contribute to the development of cell biology, qualitatively evaluate the response of cells to chemicals, and be applied to large-scale screening work for drug discovery.
In this research, we aimed for superior TFM than the conventional method and developed a novel cell traction force evaluation method using "wrinkle" generated on gold ultra-thin film. We realized visualization of the size and direction of the cell traction force and carried out basic analysis to quantify the cell traction force.
