Abstract. Cells in developing embryos behave according to their position in the organisms, and therefore seem to be receiving "Proliferation and positional information." A widespead view of the mechanism for this is that each cell responds locally to be concentration level of some extra cellular chemical, which is distributed, in a spatial gradient. For molecules conveying and receiving the proliferation and positional signal, concentrations are likely to be low enough that, per individual cell, only a few thousand molecules may be involved. In order to characterization of the structural properties of hormonal proliferation action, we proposed the construction of simple model based on hormonal generation used by Cellular Automata (CA).
