Injury Induces Endogenous Reprogramming and Dedifferentiation of Neuronal Progenitors to Multipotency

Lin et al. demonstrate that Ascl1+ and Neurog1+ neuronal progenitors can acquire cell fate plasticity after injury using genetic lineage trace and transplantation assays. Injury-induced multipotency occurs through a developmentally reminiscent endogenous upregulation of Sox2, KLF4, and Pax6, and dedifferentiation efficiency can be enhanced by Ezh2 inhibition.
