Master model: Hnf6 activates Pdx1, Ptf1a and Ngn3. Three cross-inhibition gene pairs are Ptf1a-Ngn3, Pax4-Arx and MafA-δ gene. Nodes are denoted by TF names. Arrow-heads denote activation while flat-heads denote inhibition. Circles are variable names in the mathematical model. An alternative model: Pdx1 directly inhibits both Ptf1a and Ngn3.
