Video shows Hedgehog signalling pathway. The hedgehog signaling pathway is one of the key regulators of animal development conserved from flies to humans (meaning it was present in the common ancestor of both). The pathway takes its name from its polypeptide ligand, an intercellular signaling molecule called Hedgehog (Hh) found in fruit flies of the genus Drosophila. Hh is one of Drosophila's segment polarity gene products, involved in establishing the basis of the fly body plan. The molecule remains important during later stages of embryogenesis and metamorphosis. Read more: http://en.wikipedia.org/wiki/Hedgehog_signaling_pathway
