神经前体在胚胎脑和成人脑的限制性小生境中产生神经元,这一过程称为神经发生。神经发生所需的时间和空间对细胞增殖和分化的精确控制依赖于神经前体细胞中基因转录的复杂编排。在理解神经发生的转录调控方面已经取得了很大进展,神经发生依赖于特定转录因子的剂量和环境依赖性表达,这些转录因子调节神经祖细胞的维持和增殖,然后分化为谱系特异性细胞。在这里,我们回顾了一些最广泛研究的神经源性转录因子在胚胎皮层和神经源性龛在成人大脑。我们比较了这些转录因子在胚胎和成人神经发生中的功能,突出了生物化学,发育和细胞生物学特性。我们的目标是提出一个概述的转录调控神经发生在发育中的大脑皮层和成人大脑。
Neural precursors generate neurons in the embryonic brain and in restricted niches of the adult brain in a process called neurogenesis. The precise control of cell proliferation and differentiation in time and space required for neurogenesis depends on sophisticated orchestration of gene transcription in neural precursor cells. Much progress has been made in understanding the transcriptional regulation of neurogenesis, which relies on dose- and context-dependent expression of specific transcription factors that regulate the maintenance and proliferation of neural progenitors, followed by their differentiation into lineage-specified cells. Here, we review some of the most widely studied neurogenic transcription factors in the embryonic cortex and neurogenic niches in the adult brain. We compare functions of these transcription factors in embryonic and adult neurogenesis, highlighting biochemical, developmental, and cell biological properties. Our goal is to present an overview of transcriptional regulation underlying neurogenesis in the developing cerebral cortex and in the adult brain.
