Amputated tissue from the sea cucumber Psolus fabricii persisted for three years in natural seawater, continuing to heal, grow, and diversify with immune activity observed, suggesting a new model for tissue regeneration—though it did not develop into a complete organism.
A Weizmann Institute study reveals that a subset of cells can survive radiation by keeping caspases from completing cell death, called DARE cells, which promote tissue regeneration via compensatory proliferation; their death-resistant descendants may contribute to cancer relapse, but neighboring NARE cells form a negative feedback loop to limit overgrowth.
