Fig 3. The exchange rates in two different cell communication models.

A: Configuration of 7 cells with a mean polygon number equal to 5.14. B,C: The exchange rates between the cells of panel A are shown in weighted graphs where nodes are cells and edge thickness represents the magnitude of the exchange rate. Panel B refers to the NNE communication, where only nearest neighbours can exchange the global reporter. Panel C illustrates the exchange rates in the ISD model, where also non-nearest neighbours (joined by dashed edges) can communicate via the global reporter. Parameter values: γ = 0.1 s⁻¹ for the NNE model; D = 1000.0 μm²/s and α = 1.0 s⁻¹ for the ISD model.
