A) Snapshot images showing the typical shapes of crawling PMG cells (left) and MG5 cell line (right), B) four crawling trajectories (red, PMG, total duration 56 and 25 hrs; blue, MG5, total duration 12 and 18 hrs), C) Log-log plot of mean-squared displacements vs. time interval (n = 8 for each plot), D) Blown up image showing a sequence of small zigzag turns [boxed area in (B)]. The green dots are the centroid positions and the red dots mark a turning event. In (C), the slopes of the red and blue dotted lines are 1 and 2, respectively.
