Temporal dynamics of the cell phenotype distribution (green: epithelial, yellow: hybrid E/M, red: mesenchymal) over 120 hours for the 50x50 layer of cells in the Control case (no Numb) and with Notch-Delta signalling. The final configuration of this simulation (120 hours) corresponds to the distribution presented in Fig. S9a. For this simulation, the parameters are the same of Fig. S9a.
