CK-666 induces actin-rich filopodial protrusions. Cells were imaged using differential interference contrast microscopy at a frame rate of 1 s/frame and treated with CK-666 during imaging. Cells were simultaneously fixed, permeabilized, and stained with DAPI to detect DNA (magenta) and phalloidin to detect F-actin (green). This cell is also shown in Fig. 4 G, cell 2.
