Higher organisms are characterised by a well-defined spatial structure of different tissue types. But how can such tissue patterns be formed in a (genetically) controlled way, starting from a homogeneous clump of cells? The information for cells to specialise and form different tissue types (differentiation) is carried and mediated by certain chemical messengers, called morphogens. In this seminar I will show how diffusion and interactions between morphogens ("reaction-diffusion systems") can lead to well-defined, spatially inhomogeneous, morphogen distributions that determine the spatial organisation of tissues by controlling cell differentiation. Importantly, this gives a hint how spatial information can be encoded in the genome.
This is a roughly weekly series of didactical blackboard talks focussing on some theoretical aspect of Condensed Matter, Biological, and Statistical Physics..
