Dorsoventral axis formation in Drosophila relies on extracellular signals which are generated only at the ventral side of the egg. This asymmetry, in turn, depends on the expression specifically in ventral follicle cells of pipe, the product of which seems likely to be a glycosaminoglycan-modifying enzyme.
