Evaluation Summary:
Individual cells may act in response to stimuli or in a self-organized fashion. The relative weight of these two modes determines in the end to which degree cells or rather organs/organisms carry function. This study reports an example of very complex self-organization of actin waves as the coexistence of slowly moving broad waves of high F-actin concentration and rapidly propagating planar F-actin pulses. The paper is interesting for everybody interested in conceptual questions like signalling versus self-organization, in cellular morpho-dynamics and theory of dynamic patterns.
