Fig. 9. Nomarski (left) and fluorescence (right) images of cells stained with fluorescent-phalloidin. (A,B) control, (C,D,E,F) quinine, (G,H) quinine and cytochalasin A. The image shown in F is a projection of 30 confocal sections at 0.4 µm intervals covering the entire depth of the cell. Insets in F show the sections on the distal and proximal sides of the protrusion to show that the stripes seen near the tip of the protrusion in F make up a spiral. Bar, 5 µm.
