| Outline of Final Research Achievements |
PDMS chamber was coated with low-elasticity PDMS to realize traction force microscopy in cells under mechanical stretching. In the low-elasticity PDMS, fluorescence beads were dispersed sufficiently by loading mechanical shearing. Mechanical stretching induce large displacement which make traction force microscopy difficult to quantify. To adjust the displacement, fluorescence images were correlated with fluorescence beads on which cells were not present. Although real-time traction force microscopy in cells under mechanical stretching is under construction, real-time imaging of intracellular Ca2+ increase in cells under mechanical stretching was demonstrated.
