Sea Cucumber Tissue's Longevity Could Revolutionize Biomedical Research
Researchers have discovered that tissue from a sea cucumber can survive and grow for over three years in natural seawater, challenging previous assumptions about tissue immortality. This study, led by scientists at Memorial University of Newfoundland and published in Science Advances, documented the long-term viability of amputated sea cucumber tissue outside of a controlled environment. The findings suggest that this tissue can heal and grow in a complex, microbially diverse environment, absorbing nutrients directly from seawater. This discovery opens new possibilities for biomedical research, offering a model for tissue regrowth and antimicrobial healing without the ethical and logistical challenges associated with human or vertebrate cell lines.
