Abstract  Concept & Model  Requirements  Genetic_circuit  Works  About_our_team

To follow Pareto’s principle like an ant society, our model system must follow the three conditions shown in Fig. 1 to 3. In our model, all nodes (individual cells) have the same genetic circuits but take two states, A (worker) and B (idler), depending on the surrounding circumstances.



Condition 1. Bistable state

Model1.jpg
Fig. 1 The system is stable when it contains both A (worker) and B (idler) at certain ratio.

Condition 2. Unstable state with node A removed

Model2.jpg
Fig. 2 By removal of A (worker), the system containing only B (idler)becomes unstable.

Condition 3. From unstable to stable state

Model3.jpg
Fig. 3 In the unstable state, some B (idler) changes to A (worker) while the others remain B (idler). Then the system becomes stable again.
