Unlocking epigenetic codes in neurogenesis.

During embryonic and adult neurogenesis, neuronal stem cells follow a highly conserved path of differentiation to give rise to functional neurons at various developmental stages. Epigenetic regulation--including DNA modifications, histone modifications, and noncoding regulatory RNAs, such as microRNA (miRNA) and long noncoding RNA (lncRNA)--plays a pivotal role in embryonic and adult neurogenesis. Here we review the latest in our understanding of the epigenetic regulation in neurogenesis, with a particular focus on newly identified cytosine modifications and their dynamics, along with our perspective for future studies.
