The hedgehog signaling pathway is a mechanism that directs the development of embryonic cells in animals, from invertebrates to vertebrates. The hedgehog signaling pathway is a system of genes and gene products, mostly proteins, that convert one kind of signal into another, called transduction.

The evolutionarily conserved Hedgehog (Hh) pathway is essential for normal embryonic development and plays critical roles in adult tissue maintenance, renewal and regeneration. Secreted Hh proteins act in a concentration- and time-dependent manner to initiate a series of cellular responses that range from survival and proliferation to cell fate specification and differentiation.

Hedgehog signaling pathway: an overview. The core components of the Hh pathway were initially identified in Drosophila ​ and are conserved in vertebrates, where the pathway has maintained the same mechanisms of action through species (although with some exceptions). Most interesting, deregulation of the Hh pathway leads to developmental defects and cancer.

The Mammalian HH Signaling Pathway

The Hedgehog (Hh) signaling pathway is crucial in the development of all known animals.
