title: Patterning lessons from a dorsalized embryo.
abstract: A paper by Nunes da Fonseca and colleagues in this issue of Developmental Cell shows that, to pattern its dorsoventral axis, the beetle Tribolium utilizes many of the same genes used in flies, but in very different ways: rather than relying on maternal information, it uses Dorsal and Dpp as part of two coordinated ancestral self-organized systems.
