Hedgehog: an unusual signal transducer

Article Abstract:

The functions and the features of Hedgehog proteins in both normal and pathological growth control are discussed. The Hedgehog proteins are of significant importance in the development and maintenance of tissue patterns in human adults, however Hedgehog signaling is a field which is least understood, the idiosyncratic features reflects its ancient evolutionary past.
