Fig 7. Steady state behavior of the PTGs and DTGs as functions of the parameter A upon h = 6, a₃ = 14.5, a₇ = 14.

Abscissas of the turning points of w₁ and w₂ curves with values $A_{*}^{\mathit{||}}=0.1531$ and $A_{*}^{\mathit{|}}=0.2653$ determine the limits of the bistable behavior (marked by asterisks). As the parameter A is boosted beyond $A_{*}^{\mathit{|}}=0.2653$, the core network switches to the pluripotent state, while when the external signal is dropped below $A_{*}^{\mathit{||}}=0.1531$, the system switches to differentiation state.
