Fig 8. The bistable switch in the core network depending on (a3, a7) parameters and at h = 6. Highlighted region is the parameters range, for which the switch-like behavior has existed.
Furthermore, the analysis indicated that a straight line a3 = a7 in the plane (a3, a7) divides it into two areas. When a3 < a7, there will be some A0, that upon A > A0 the cell is pluripotent, while at A < A0 the cell will differentiate. When a3 > a7, the cell has pluripotent state at all values A ≥ 0.
