Tissues taken from sea cucumbers remain intact for three years in natural seawater
Sea cucumbers are known for their regenerative capacity and for exhibiting minimal cellular ageing. An article published in the journal Science Advances has documented the viability of amputated tissue from the species Psolus fabricii for over three years in natural seawater. Samples taken from three individuals of this species showed cellular diversification, immune activity, tissue reorganisation and the uptake of dissolved amino acids—properties that are unparalleled in the current scientific literature, according to the article. The authors also note that the finding may pave the way for a new experimental model, free from ethical concerns, for regenerative biology, biomedical research and tissue engineering.
