Can Cells from a Sea Cucumber Live Forever?
Recent research has revealed that cells from a specific species of sea cucumber, Psolus fabricii, exhibit remarkable regenerative capabilities. These cells can survive and thrive for years after being separated from their host, challenging previous notions of cellular immortality. The findings prompt a reevaluation of what it means for tissue to be considered alive.
- ▪Marine biologists from Memorial University discovered that explants from the sea cucumber Psolus fabricii can live for years after being cut from the organism.
- ▪These explants showed no signs of decline and were able to absorb nutrients from seawater, fueling regeneration and immune activity.
- ▪The researchers termed these living tissue blobs 'LiPfe,' highlighting their unique characteristics that blur the lines between organismal life and cellular autonomy.
