Aging is associated with cellular senescence, mitochondrial dysfunction, chronic inflammation, and impaired regenerative capacity across multiple tissues. Hedgehog signaling, through coordinated canonical and non-canonical pathways, suppresses senescence-associated phenotypes, supports metabolic and transcriptional homeostasis, and promotes tissue protection and regeneration in diverse organs, thereby contributing to the maintenance of organismal healthspan.
