Stress and BCL2T concentrations control cell apoptosis. A color-code identical to that of Figure 2 panel C1 was assigned to both stress and BCL2T variations; see Table 2 for the subinterval definition. Scatter plots of variables versus stress variations at time t = 500 were then evaluated, and they are here reported for BAXmT (panels A and B) and BH3 (panels C and D), colored for both color-codes. Specifically, panels A and C are colored for stress, while panels B and D are colored for BCL2T. Both BAXmT and BH3 can be found in two different configurations, depending on the concentrations of stress and BCL2T.
