Differential diffusivity of the Turing morphogens

Publication date: Available online 27 September 2018Source: Progress in Biophysics and Molecular BiologyAuthor(s): Yoram SchiffmannAbstractThe Turing morphogens cAMP and ATP are considered as electrolytes. Each is made of a slow anion and fast cation. The unequal diffusion of the of the cation and the anion creates an electric field which accelerates the anion and decelerates the cation. This effect is more pronounced for ATP than cAMP since ATP has higher charge and greater concentration than cAMP.
