Figure 3. Downregulation of LIMK1 decreases actin polymerization and focal adhesion formation. Corneal fibroblasts transfected with TransIT-TKO transfection reagent, a 100 nM scrambled or LIMK1 siRNA for 72 h were fixed and permeablized. The cells were stained for actin (green color, using Alexa 488 phalloidin) and paxillin (red color, using anti-paxillin and Cy3-goat anti-mouse IgG) where indicated. The nuclei were stained with DAPI (blue color). Note the reduction of actin stress fibers and paxillin-positive focal adhesions in LIMK1 siRNA-transfected cells. Bar, 20 μm.
