Sea Cucumber Tissue Thrives Three Years, Boosting Regeneration Research

5/29/2026

Summary

Story summary

Severed tissue from sea cucumber Psolus fabricii survived, healed and grew for three years in seawater.
Researchers at Memorial University of Newfoundland and Bigelow Laboratory reported the tissue remained alive, diversified, showed an immune response and directly absorbed dissolved amino acids.
Published in Science Advances on May 27, the study challenges tissue-immortality assumptions and may aid wound healing, antimicrobial treatment and tissue regeneration, providing a low-regulation model for labs and education.
