Relation between saltatory movements and mean cell speed in E15 lattice cultures. A) Cumulative distance plots from 3 representative cells (of 38 cells analyzed) showing distinct mean speeds. B) Speed plots of the same cells as in A, showing differences in the number and size of saltatory movements (steps). C) Step frequency and D) mean step distance were plotted against the mean speed of the same cell. E) Mean step distance compared to mean step duration (closed circles, left Y-axis) and mean step speed (open boxes, right Y-axis) in the same cell. Quartiles are based on mean cell speed (C, D) or mean step distance (E) and are identified underneath the relevant plots (1Q = 1st quartile).
