Collective cell rotation driven by a portion of cells with persistence force. Here, colored cells can exert persistent force whereas the remaining cells are passive. (a) Number of cells with persistent force is M = 20. The persistent force magnitude is α = 0.1. (b) M = 10 and α = 0.15. (c) M = 4 and α = 0.25. (d) M = 3 and α = 0.25. The total number of cells in the system is N = 50. In these simulations, we take β = 0.1 and σ = 0.002. To see this figure in color, go online.
