Temporal correlation between fluctuations in CC activity and soma translocation. (a) Line scan of the stress along the typical GC axis (left) and soma translocation (right) with time for the same migrating GC. Green dot, location of the dominant CC; cyan line, soma center. Additionally, four more cases were shown in Fig. S3, and a total number of 28 migrating GCs were summarized in Fig. 2 e. (b) Soma displacements during the boxed period in a. (c) Stress during the period marked by the box in a. Black line, period of forward soma translocation, when the contractile activity of the CC at LP was higher; gray line, rearward soma translocation when the contractile activity of the CC at the TP was higher. (d) Stress differential representing the change in the stress (ΔF over Δt = 15 s) for the same period as in c. Boxed areas are shown at a higher spatial resolution below. White circles, the region with the highest change in the direction of stress differential, indicating CC location. Note the increase and decrease of stress differential (ΔF over 15 s) at a dominant CC at pLP, followed by another dominant CC at TP. Red lines, cell outline.
