✦ Synopsis

Competence is an active state that defines the way in which cells respond to an inductive signal. A challenge of developmental biology is to explain not just the nature of the signalling molecules that promote cell specification or differentiation, but also how cells acquire competence to respond to these signals and what that reflects in molecular terms. A recent paper by Carmena et al. has revealed how several signalling mechanisms are used sequentially and in specific combinations to specify two mesodermal lineages in Drosophila. BioEssays 21:455-458, 1999.

During gastrulation in vertebrates the cells of the embryonic ectoderm give rise to epidermal progenitors in the ventral side and neural progenitors in the dorsal side. Despite many years of scrutiny, the molecular basis of these important embryonic cell fate decisions have not been solved. Only rec
