"Unlocking the Mystery: The Rapid Tentacle Regeneration of Jellyfish"

Researchers from the University of Tokyo and Tohoku University have discovered how jellyfish regenerate their tentacles, a process that involves the formation of a blastema, similar to that in amphibians and other regenerating animals. The blastema is formed by proliferative cells that appear at the injury site and work in conjunction with localized stem cells to regrow the tentacle. This process in jellyfish, which are cnidarians with radial body symmetry, is surprisingly similar to that of bilaterian animals, which have bilateral symmetry. Understanding jellyfish regeneration could potentially inform future regenerative treatments in humans, although such applications are currently speculative.
