'Using single i-cell transplantation from transgenic fluorescent donors to wild-type recipients, we find that these cells are pluripotent. Under physiological conditions, a single i-cell can differentiate into all somatic cell types and into gametes. The presence of embryonic-like, pluripotent cells throughout adult life facilitates their ability to grow indefinitely in a plant-like fashion.'
