Abstract
This study uses inducible ablation of NeuroD1 from adult neuronal stem cells/progenitors to show that this transcription factor is crucial for the survival and maturation of adult-born neurons in the hippocampus and olfactory bulb. The transcriptional program that controls adult neurogenesis is unknown. We generated mice with an inducible stem cell–specific deletion of Neurod1, resulting in substantially fewer newborn neurons in the hippocampus and olfactory bulb. Thus, Neurod1 is cell-intrinsically required for the survival and maturation of adult-born neurons.
