Snapshots of aggregation at different elapsed times. cAMP concentration on the left and cell distribution on the right. Same γ scale as in Fig. 3, gray squares show where cells are present and empty spaces are shown in black. Density = 4 · 105 cells/cm2 (0.4 mono-layer) and ke = 5.7 min−1. (a) t = 30 min, (b) t = 75 min, (c) t = 100 min, and (d) t = 150 min.
