哺乳动物的神经系统由许多不同的神经元亚型组成,每种亚型都有自己的表型和对退行性疾病的不同敏感性。虽然可以从啮齿动物胚胎中分离出特定的神经元类型,或者从干细胞中设计出特定类型的神经元进行翻译研究,但转录因子介导的重新编程可能提供了一条更直接的途径来产生它们。在此,我们报道了选择转录因子的强制表达足以将鼠和人成纤维细胞转化为诱导运动神经元(IMN)。IMN在形态、基因表达特征、电生理、突触功能、体内植入能力和对退行性刺激的敏感性等方面表现出与胚胎来源运动神经元相似的特征。我们发现,转化的成纤维细胞不会通过增殖的神经前体状态,从而通过不同于胚胎发育的途径形成真正的运动神经元。我们的发现表明,成纤维细胞可以直接转化为一种特定的分化和功能神经亚型,即脊髓运动神经元。
The mammalian nervous system is composed of a multitude of distinct neuronal subtypes, each with its own phenotype and differential sensitivity to degenerative disease. Although specific neuronal types can be isolated from rodent embryos or engineered from stem cells for translational studies, transcription factor mediated reprogramming might provide a more direct route to their generation. Here we report that the forced expression of select transcription factors is sufficient to convert mouse and human fibroblasts into induced motor neurons (iMNs). iMNs displayed a morphology, gene expression signature, electrophysiology, synaptic functionality, in vivo engraftment capacity and sensitivity to degenerative stimuli, similar to embryo-derived motor neurons. We show that the converting fibroblasts do not transit through a proliferative neural progenitor state, and thus form bona fide motor neurons via a route distinct from embryonic development. Our findings demonstrate that fibroblasts can be converted directly into a specific differentiated and functional neural subtype, the spinal motor neuron.
