A focused laser beam was used to induce strain sites in stress fibers of fibroblasts transfected with mApple-actin and EGFP-tagged XIRP2-LIM domain. Cells were imaged for 3 min and 30 s, alternating between the actin and XIRP2-LIM channel, with images taken approximately every 2 s. After 30 s of imaging the steady state, 5 μm region was illuminated with the 405 laser to induce a strain site via photoablation. The remainder of the time lapse was then imaged. EGFP-tagged XIRP2-LIM showed no recruitment to ablation sites.
