Hedgehog signaling

Hedgehog signaling is a biological pathway that helps cells communicate to control tissue development and maintain healthy cell functions. Named after the "Hedgehog" gene discovered in fruit flies, it involves proteins that transmit signals from outside the cell to the inside, influencing how cells grow, divide, and specialize. This pathway is crucial during embryonic development and tissue regeneration. When functioning properly, it ensures tissues form correctly; however, if the pathway malfunctions, it can lead to issues like developmental defects or cancers. Overall, it’s a key mechanism that guides proper growth and organization in the body.
