Evidence emerges that redox gradients regulate morphogenesis, inflammation, regeneration, and healing of tissues. At the example of redox signaling during the zebrafish wound response, I briefly discuss current ideas on how such patterns might be sensed and spatially regulated to guide physiological processes over distances in animals.
