"Unlocking the Mystery of Rapid Tentacle Regeneration in Jellyfish"

Researchers at the University of Tokyo have uncovered the cellular mechanisms that allow jellyfish to regenerate their tentacles. They found that jellyfish use repair-specific proliferative cells, similar to stem cells, to regrow their tentacles. These cells are different from the resident stem cells and only appear when the jellyfish is injured. This discovery not only sheds light on the regenerative abilities of jellyfish but also suggests a potential for convergent evolution with other regenerative species like salamanders. Understanding these mechanisms could have implications for improving human regenerative medicine. The study was published in PLOS Biology.
