在胚胎发育过程中,未承诺的多能细胞经历了渐进的表观遗传变化,将它们锁定在最终的分化状态。哺乳动物细胞能在生物体内部改变身份吗?细胞的直接谱系重编程作为实现器官再生的一种手段引起了人们的关注。然而,尚不清楚中枢神经系统中的细胞是否具有重编程的可塑性。神经元尤其被认为是最不可变的细胞类型之一,能够在生物体的生命周期中保持其类别特异性特征。在这里,我们关注两个实验范式,胶质细胞到神经元和神经元到神经元的转换,考虑谱系重编程如何挑战中枢神经系统不变性的概念,为重编程策略在体内重塑神经元和电路的应用铺平道路。
During embryonic development, uncommitted pluripotent cells undergo progressive epigenetic changes that lock them into a final differentiated state. Can mammalian cells change identity within the living organism? Direct lineage reprogramming of cells has attracted attention as a means to achieve organ regeneration. However, it is unclear whether cells in the CNS are endowed with the plasticity to reprogram. Neurons in particular are considered among the most immutable cell types, able to retain their class-specific traits for the lifespan of the organism. Here we focus on two experimental paradigms, glia-to-neuron and neuron-to-neuron conversion, to consider how lineage reprogramming has challenged the notion of CNS immutability, paving the way for the application of reprogramming strategies to reshape neurons and circuits in vivo.
