Abstract
Morphogens are typically distributed symmetrically from their source of production. In this issue of Developmental Cell, Peng et al. (2012) demonstrate that a bias in the directionality of protrusions emanating from cells secreting the EGFR ligand Spitz leads to asymmetric activation of the pathway.
