Yet Another Scenario of Pattern Formation: Interpretation of Position Information

During the development process, how the position information is determined is one of the most important issue. We propose a scenario that the pattern are generated from a class of discrete reaction-diffusion system, in which the character of every single cell varies according to space distribution. Using the key feature of wave propagation failure, we can observe and even design various pattern. It takes a different scenario from the well known Turing structure.
