Fig 9. Characterization of actin dynamics by live cell TIRF-SIM imaging.

Fig 9

Frames taken from time-lapse TIRF-SIM videos of n = 3 representative Lifeact-GFP mouse platelets from either Pdlim7-/- or WT genetic backgrounds spreading on glass (see S1 and S2 videos). WT platelets (top row) showing the dynamic nature of actin cytoskeleton formation. Pdlim7-/- platelets (bottom row) demonstrating a dramatically altered spatiotemporal-resolved organization of the F-actin, resulting in a significantly deformed cytoskeletal shape. Arrows indicate areas of dynamic polymerization of F-actin filaments. After 3 to 4 minutes of illumination photobleaching becomes apparent; loss of fluorescence intensity was compensated for by adjusting exposure to +3 using Photoshop software for Pdlim7-/- platelets. Time stamp = mins. Scale bar = 5 μm.
