When starved, Schmidtea undergoes degrowth, during which some of its cells are cannibalized by others. A continual cell turnover underlies this phenomenon: the differentiated cells in the animal's body are continually replaced by division and differentiation of stem cells called neoblasts. Remarkably, a single healthy neoblast is sufficient to rescue a lethally irradiated animal from death.
