细胞分化和谱系定型被认为是发育过程中稳健且不可逆的过程。最近的研究表明,小鼠和人类成纤维细胞可以通过四种转录因子的组合重新编程为多能状态。这就提出了一个问题,即转录因子是否可以直接诱导其他定义的体细胞命运,而不仅仅是未分化的状态。我们假设神经谱系特异性转录因子的组合表达可以直接将成纤维细胞转化为神经元。从19个候选基因的库开始,我们确定了仅三个因子的组合,Ascl1,Brn2和Myt1l,足以在体外快速有效地将小鼠胚胎和出生后的成纤维细胞转化为功能性神经元。这些诱导的神经元(iN)细胞表达多种神经元特异性蛋白,产生动作电位,并形成功能性突触。从非神经谱系产生iN细胞可能对神经发育,神经疾病建模和再生医学的研究具有重要意义。
Cellular differentiation and lineage commitment are considered robust and irreversible processes during development. Recent work has shown that mouse and human fibroblasts can be reprogrammed to a pluripotent state with a combination of four transcription factors. This raised the question of whether transcription factors could directly induce other defined somatic cell fates, and not only an undifferentiated state. We hypothesized that combinatorial expression of neural lineage-specific transcription factors could directly convert fibroblasts into neurons. Starting from a pool of nineteen candidate genes, we identified a combination of only three factors, Ascl1, Brn2, and Myt1l, that suffice to rapidly and efficiently convert mouse embryonic and postnatal fibroblasts into functional neurons in vitro. These induced neuronal (iN) cells express multiple neuron-specific proteins, generate action potentials, and form functional synapses. Generation of iN cells from non-neural lineages could have important implications for studies of neural development, neurological disease modeling, and regenerative medicine.
