Plasticity in Olfactory Epithelium: Is It a Sniffer or Shape Shifter?

Precise lineage trajectories and the cellular sources that contribute to regeneration after injury are largely unknown in many tissues. In this issue of Cell Stem Cell, Gadye et al. (2017) and Lin et al. (2017) show that olfactory epithelial cells transit through unique and unfamiliar paths of differentiation and undergo lineage reversion, respectively, during regeneration.
