title: Axon guidance: morphogens show the way.
abstract: Hedgehog and Wnt family proteins can act as classic developmental morphogens to pattern a field of nai;ve cells. Surprising new studies show that members of these same protein families also act as guidance cues for growing axons in the developing nervous system.
