Jellyfish can heal wounds in minutes. Scientists want their secrets
Scientists are studying the jellyfish species Clytia hemisphaerica to understand its unique ability to heal wounds rapidly without scarring. Because these jellyfish are transparent and lack a complex immune system, they provide a clear model for observing cellular regeneration in real time.
A decade ago this summer, at the Marine Biological Laboratory, Jocelyn Malamy watched jellyfish cells “walk” toward each other to close a wound for the first time. An associate professor in Molecular Genetics and Cell Biology at the University of Chicago, Malamy had received transparent, dime-sized medusae of the species Clytia hemisphaerica from Evelyn Houliston’s lab at the Marine Observatoire in Villefranche.
