Abstract
Early neural fate commitment is a key process in neural development and establishment of the central nervous system, and this process is tightly controlled by extrinsic signals, intrinsic factors, and epigenetic regulation. Here, we summarize the main findings regarding the regulatory network of epigenetic mechanisms that play important roles during early neural fate determination and embryonic development, including histone modifications, chromatin remodeling, DNA modifications, and RNA-level regulation. These regulatory mechanisms coordinate to play essential roles in silencing of pluripotency genes and activating key neurodevelopmental genes during cell fate commitment at DNA, histone, chromatin, and RNA levels. Moreover, we discuss the relationship between epigenetic regulation, signaling pathways, and intrinsic factors during early neural fate specification.
