Since their isolation in the early 1990s, members of the Hedgehog family of intercellular signaling proteins have come to be recognized as key mediators of many fundamental processes in embryonic development. Their activities are central to the growth, patterning, and morphogenesis of many different regions within the body plans of vertebrates and insects, and most likely other invertebrates. In some contexts, Hedgehog signals act as morphogens in the dose-dependent induction of distinct cell…

Several pieces of evidence support the notion that this patterning of larval wing imaginal discs is mediated by a direct morphogen activity of Shh, and the cell-autonomous activation or inactivation of the pathway using mutant forms of receptor components results in autonomous changes of cell fates, confirming the direct role of Hh signaling.

Hh signaling has been recognized during embryonic development and in some cases during postnatal life in several mammalian tissues whose functions are essential for reproduction, including the gonads, uterus, and hormonally responsive accessory sex glands such as the prostate and mammary gland.

This work addresses the question of whether the Hh pathway is distally branched or, in other words, whether the regulation of Ci activity is the sole output of Hh signaling and proposes that most cases of apparent Ci/Gli-independent Hh output can be attributed to the derepression of target gene expression in the absence of Ci/gli repressor function.

It is shown that new members of this family isolated from Xenopus laevis are expressed embryonically in patterns suggestive of roles in patterning in the ectoderm, nervous system and somites, and banded hedgehog is expressed throughout the neural plate and subsequently in both the nervousSystem and in the dermatome of somites.

Evidence is presented that transduction of the hh-encoded signal is mediated by the activity of four other segment polarity genes, patched, fused, costal-2 and cubitus interruptus, and that transcription of patched is regulated by the same pathway.

Optimized immunohistochemistry combined with tissue separation and biochemical analyses in vivo and in vitro are used to determine the range of action of SHH and IHH in the mouse embryo, suggesting a direct long-range action without a need for secondary mediators.

It is shown that the role of patched in positional signalling is permissive rather than instructive, its activity being required to suppress wingless transcription in cells predisposed to express the latter.
