In this issue of Cell, Sustar and Schubiger (2005) address a longstanding question in regeneration biology: How is pluripotency achieved during regeneration? The authors have examined the cell cycle and growth characteristics of multipotent regenerating and transdetermining Drosophila cells and come up with some surprising findings.
