As embryos develop, cells differentiate and produce new repertoires of gene regulatory proteins. Conventional studies that look at just one or a few genes at a time do not reveal which events drive such dynamic changes. Peter and Davidson now present a functional dissection of the large gene regulatory network involved in meso-endodermic specification in the sea-urchin embryo.
