To provide a comprehensive understanding of gene regulatory networks in the developing human brain and a foundation for interpreting pathogenic deregulation. We generated reference epigenomes and transcriptomes of dissected brain regions and primary neural progenitor cells (NPCs) derived from cortical and ganglionic eminence tissues of four normal human fetuses. Integration of these data across developmental stages revealed a directional increase in active regulatory states, transcription factor activities and gene transcription with developmental stage. Consistent with differences in their biology, NPCs derived from cortical and ganglionic eminence regions contained common, region specific, and gestational week specific regulatory states. We provide a high-resolution regulatory network for NPCs from different brain regions as a comprehensive reference for future studies.
为了全面了解人类大脑发育过程中的基因调控网络,并为解释致病基因失活提供基础。我们生成了四个正常胎儿大脑区域和皮质及神经节隆起组织来源的原代神经前体细胞(NPC)的参考表观基因组和转录组。通过跨发育阶段的整合,这些数据揭示了活性调控状态、转录因子活性和基因转录随发育阶段呈定向增加的趋势。与它们生物学差异一致,源自皮质和神经节隆起区域的 NPC 包含常见的、区域特异性的和妊娠期特异性的调控状态。我们为不同脑区的 NPC 提供了一个高分辨率的调控网络,作为未来研究的综合参考。
