Abstract excerpt
Sonic hedgehog (Shh) expression in the developing limb is associated with the zone of polarising activity (ZPA), and both are restricted to the posterior part of the limb bud. We show that the expression patterns of Shh and Gli3, a member of the Gli-family believed to function in transcriptional control, appear to be mutually exclusive in limb buds of mouse embryos. In the polydactyly mouse mutant extra toes...
