The Hedgehog (Hh) signaling pathway is a fundamental regulator of embryonic development across animal species. Initial discoveries of Hh signaling came from studies in Drosophila, where it was shown to be critical for both embryogenesis and metamorphosis.
The Hedgehog (Hh) signaling pathway is one of the core pathways regulating embryonic development in animals. Initially discovered in Drosophila, it plays a decisive role in embryogenesis and metamorphosis. In mammals, this pathway involves three homologous ligands: Sonic Hedgehog (SHH), Desert ...
