Figure Lengend Snippet: The PC9 cells was seeded on 5-kPa PAA gel and imaged for over 10 hours after attaching. ( A ) YAP expression is represented by green fluorescence intensity. Note: The YAP intensity becomes homogenous from the 1.5 th hour on. (B) Substrate deformation (overlapped with the bright-field image) at cell location is represented by fluorescent beads displacement field at each time point. Displacement direction and magnitude are shown by the arrow direction and color, respectively. The displacement field caused by PC9 cells is smaller compared to that caused by the B2B cell. Throughout the 10-hour spreading process, the area of PC9 cells nearly remains constant. (C) Traction field (overlapped with the bright-field image) calculated from displacement field. The traction generated by this representative PC9 cell gradually decreases from the 6 th hour to the 10 th hour.
