Figure 10.

Actin stress fiber rotation in response to applied static strain (horizontal arrows indicate stretch direction). (a) and (b) are the original and stretched (11%) configuration respectively where the red dotted region indicates the stress fibers tracked. (c) Actin stress fiber rotation as a function of time (shown for 5 stress fibers). Here it is clear that the actin stress fiber reorientation occurs within minutes of applied strain. The small inset in the lower right schematically illustrates the stress fiber rotation where θ₁ is the initial angle and θ₂ is the final angle relative to the strain direction. (scale bar = 30 µm)
