Noise sensitivity and rescue. (A) τ-leaping simulations of uncoupled cells, showing the averages over 30 individual trajectories as a function of time for different durations of exposure to M (i–vi). (B) Average final concentration for (C) as a function of space, assuming cells are arranged as in Fig. 3A. (C) Heuristic approach used for the coupling. (D) Shape of the reaction force used to model coupling between cells. (E) Average of 30 cells using τ-leaping simulations of coupled cells within a full embryo as a function of time for different durations of exposure to M (i–vi). Rescue is almost perfect. (F) Average final concentration for same simulation as in (E). To see this figure in color, go online.
