515-人内侧神经节隆起发育的分子与空间图谱

from 聊聊Sci

这项研究揭示了人类大脑中一种名为室下区放射状胶质细胞(SVZ RGC)的新型神经前体细胞,它在抑制性神经元的产生中起着至关重要的作用。科学家发现,这种特定的细胞群在人类和猕猴等灵长类动物中存在,但在小鼠中缺失,这解释了人类大脑皮层中抑制性神经元比例显著增加的进化原因。通过单细胞测序和实时成像技术,研究人员观察到这些细胞具有独特的单极形态和有丝分裂体易位行为。此外,研究还指出这些前体细胞及其衍生的神经元与自闭症谱系障碍等神经发育疾病的风险基因高度相关。这一发现不仅完善了人类大脑发育的细胞图谱,也为理解人类特有的认知能力提供了生物学基础。References:* Jia L, Li X, Yan Y, et al.
