Fig. 2.

Center-based computational model of multicellular dynamics. (a) Schema of a local cell neighborhood and the abstract forces on cell centers. 𝐹→AR𝑗𝑖 ${\vec{F}}_{j i}^{AR}$ is the passive AR force exerted on a cell i by a cell j. 𝐹→Pol𝑖 ${\vec{F}}_{i}^{Pol}$ is the active migration force driven by the cell’s polarity (specified in Section 3.4). (b) Plot of the Morse force profile (derivative of the Morse potential) defining 𝐹→AR ${\vec{F}}^{AR}$ , for different parameter values. This curve presents two regimes: a positive regime (attraction) below an equilibrium distance 𝑟eq $r_{eq}$ and a negative regime (repulsion) above
