FIGURE 4:

Effect of CK₂β removal on cell size, traction force, and migration speed. (A) Only a single population of ΔCK2β cells was identified based on size distribution. Six independent experiments, 101 cells. (B) Comparison of the proportion of small (>56 µm; blue) and large cells (>56 µm; red) in WT and ΔCK2β cells. (C, D) Contractile energy and migration speed of small (C) and large (D) ΔCK2β cells compared with WT cells. (E) Contractile energy and speed of the entire population of ΔCK2β cells compared with small, large, or entire population of WT cells. Data for WT cells are reproduced from Figure 2.
