From: Spontaneous center formation in Dictyostelium discoideum
Image of a numerical simulation showing a signaling center with the characteristics of those observed by Ohta et al.30. Density = 1.25 · 105 cells/cm2 (0.125 mono-layer), ke = 1.56 min−1. (a) cAMP concentration in the areas occupied by cells, with equal concentration levels of the whole extracellular media. (b) Zoom of the signaling center marked with red in (a) showing the percentage of active receptors ρ. Cells with lower ρ (dark purple) are those which initially fire. Around 18 cells constitute the firing center.
