Figure 2A. PC-3M cells displaying stretched actin fibers with long exon-type extensions (Control). CT (50 nM)-stimulated cells exhibit long actin-rich extensions resembling filopodia or web-like actin-containing fibers linking these filopodium-like structures (CT).

Figure 2B. Addition of latrunculin A (50 nM) resulted in rapid changes in cell morphology and actin distribution as characterized by the remarkable shrinkage of actin stress fibers (Lat A and Lat A+CT).
