Fig. 11. Centroid tracks of control C3 (A) and mutant m4-65 cells (B) during wound healing. The interval between adjacent centroid is 5 minutes. Persistent, rapid movement in C3 cells was reflected by a linear track and well-separated centroids with time (A). By contrast, little translocation with frequent direction change in mutant m4-65 cells was represented by a zigzag track and clusters of centroids with time (B). Scale bar, 10 µm.
