Fig 6. The bistable switch in the core network depending on (a3, a7) parameters and at h = 6.
Highlighted region is the range of parameter values, having which the system has switch-like behavior. Furthermore, the analysis indicated that a straight line a3 = a7 divides the plane (a3, a7) it into two areas. When a3 < a7, the cell has differentiated state at all values A ≥ 0. When a3 > a7, there will be some A0, that upon A > A0 the cell is pluripotent, while at A < A0 the cell will differentiate.
