GABA能中间神经元调节哺乳动物大脑皮层的神经回路活动。这些皮质中间神经元在结构和功能上是多样的。在这里,我们使用单细胞转录组学来研究小鼠中这种多样性的起源。我们确定不同类型的祖细胞和新生神经元的神经节隆起,胚胎增殖区,产生皮层中间神经元。这些胚胎前体显示出时间和空间限制的转录模式,导致成年大脑皮层中不同类别的中间神经元。我们的研究结果表明,中间神经元成为有丝分裂后不久,他们的多样性已经在其不同的转录程序,随后指导进一步分化的发展皮层专利。
GABAergic interneurons regulate neural circuit activity in the mammalian cerebral cortex. These cortical interneurons are structurally and functionally diverse. Here we use single-cell transcriptomics to study the origins of this diversity in mouse. We identify distinct types of progenitor cells and newborn neurons in the ganglionic eminences, the embryonic proliferative regions that give rise to cortical interneurons. These embryonic precursors show temporally and spatially restricted transcriptional patterns that lead to different classes of interneurons in the adult cerebral cortex. Our findings suggest that shortly after the interneurons become postmitotic, their diversity is already patent in their diverse transcriptional programs which subsequently guide further differentiation in the developing cortex.
