From: Theoretical basis of the community effect in development
A minimal model of a community effect. (A) A schematic depiction of the model. Each molecule or state is indicated in red, and arrows indicate reactions/transitions between those states with reaction rate parameters as indicated. See text for details. (B) Steady state of [x] plotted as a function of community size n. Parameter values used for the plot are: k1, k2, k3 = 0.02; δ1, δ 2, δ 3 = 0.01; V c = 1; V s = 800.
