Migration analysis of the OPC depicted in Fig 4. (A) Trajectories of the origin of the frontal process (red), the maximum cell height (green) and the origin of the rear process (blue) superimposed on the top-view of the data of the first scan (Fig. 4 A); inset shows the magnified trajectories (rearranged for clarity). (B) Difference image between first and last scan. Lateral scale bars in (A) and (B) represent 3 μm. (C) Plots of the velocities of each of the three points of observation as defined in (A).
