Abstract:
The segment polarity gene hedgehog plays a central role in cell patterning during embryonic and post-embryonic development of the dipteran, Drosophila melanogaster. Recent studies have identified a family of hedgehog related genes in vertebrates; one of these, Sonic hedgehog is implicated in positional signalling processes that show interesting similarities with those controlled by its Drosophila homologue.
