Intra–inter dynamics approach is presented to study a biological system. It consists of units with internal dynamics, interaction among them, and their replication (and death) according to their internal states. Based on such scheme, a novel picture on a biological system is given, which...

A dynamical systems scenario for developmental cell biology is proposed, based on numerical studies of a system with interacting units with internal dynamics and reproduction. Diversification, formation of discrete and recursive types, and rules for differentiation are found as a natural...
