Genome-wide map of SOX21 occupancy in human embryonic stem cell-derived neural progenitor cells [ChIP-seq]
To understand how SOX21 regulates neural fate specification, we differentiated wild type and SOX21 knockout hESC into neural epithelial cells (NECs) using dual SMAD inhibition protocol. We collected cells at neural differentiation day 5 and performed SOX21 ChIP-seq to investigate the genome-wide binding profiles. Meanwhile, we also carried out b-catenin ChIP-seq in wild type and SOX21 knockout NECs to dissect the role of SOX21 in Wnt signaling inhibition, thus providing important information for the mechanism underlying SOX21's functions in early neural fate specification. Overall design: Examination of genome-wide binding profile of SOX21 in neural epithelial cells (NECs). Comparison of b-catenin occupies between wild type and SOX21 knockout NPCs.
