Self-Reproduction Cellular Automata Model to Construct Artificial Cell (Hybrid Model Use of Cellular Automata Model and Gray Scott Model)

Abstract

Understanding the generalized mechanism of self-reproduction is considered to be fundamental for application in various fields such as mass-production of molecular machines of nanotechnology. We developed a model for simulating cellular self-reproduction in two-dimensional hybrid cellular automata. To reduce the transition rules number, we considered not only the state transition rules but also the concentration diffusion of the Gray Scott model, which emerges self-reproduction phenomenon with certain parameters. In this hybrid model, information carriers activate the trigger of the self-reproduction phenomenon of the Gray Scott model, and cell membrane was formed by a part of the specific concentration of Gray Scott model. Using this model, we demonstrated that the following 3 functions can be realized. (1) Formation of a border similar to cell membrane. (2) Self-replication is achieved while maintaining a carrier containing information. (3) The division of the cell membrane is achieved while maintaining the total structure.
