Testing Turing’s theory of morphogenesis in chemical cells validated

See on Scoop.itBiobit: Computational Neuroscience & Biocomputation

Alan Turing, in “The Chemical Basis of Morphogenesis”, described how, incircular arrays of identical biological cells, diffusion can interact with chemical reactions to generate up to six periodic spatiotemporal chemical structures. Turing proposed that one of these structures, a stationary pattern with a chemically determined wavelength, is responsible for differentiation.  Quantitative experimental results obtained using this artificial cellular system establish the strengths and weaknesses of the Turing model, applicable to biology and materials science alike, and pinpoint which directions are required for improvement.
