(A1) The micropillars do not deflect just before attachement. (A2) The total strain (ε_total) was measured by examining rose Bengal fluorescence of the micropillars after cell attachment. (A3) The viscous part of the total strain (ε_D) was measured after cell detachment by trypsinization for 15 min at room temperature. The elastic part of the total strain (ε_E) was calculated as ε_total minus ε_D. (B1,B2) The bending of the micropillars with the color bar indicates the depth of the image (B1) before and (B2) after cell detachment. Scale bars, 10 μm.
