The cerebral cortex contains dozens of neuronal subtypes grouped in specific layers and areas. Recent studies have revealed how embryonic and induced pluripotent stem cells (PSC) can differentiate into a wide diversity of cortical neurons in vitro, while recapitulating many of the temporal and spatial features that characterize corticogenesis. PSC-derived neurons can integrate into the brain following in vivo transplantation and display patterns of morphology and connectivity specific of cortical neurons. PSC-corticogenesis thus emerges as a robust model that provides new ways to link cortical development, evolution, and disease.
大脑皮层包含数十种神经元亚型,这些亚型按特定的层和区域分组。最近的研究揭示了胚胎干细胞和诱导多能干细胞(PSC)如何在体外分化为多种多样的皮层神经元,同时重现了许多构成皮质发生特征的时空特征。PSC衍生的神经元在体内移植后可以整合到大脑中,并表现出皮层神经元特有的形态和连接模式。因此,PSC-皮质发生成为一个强大的模型,为连接皮层发育、进化和疾病提供了新的途径。
