MeSH definition : A family of intercellular signaling proteins that play and important role in regulating
the development of many TISSUES and organs. Their name derives from the observation
of a hedgehog-like appearance in DROSOPHILA embryos with genetic mutations that block
their action.; A family of intercellular signaling proteins that play an important role in regulating
