The most important and underlying points of our model is that the system is stable against environmental changes when two or more types of individuals coexist, called "coexistence stability." Our project have aimed at this "coexistence stability," not dynamic equilibrium such as chemical ones

共存安定をなりたたせるために必要な要素は以下の３つである １．双安定 ２．Cell－Cellコミュニケーション ３．２つの機能が１つの細胞から実現されること
To achieve this “coexistence stability,” our model requires
1. bistability
2. cell-cell communication

それぞれについて以下で説明する。

１、双安定

これがないと、動的平衡になってしまう。
