成体神经发生是从成体神经前体产生功能性神经元的过程,发生在哺乳动物一生中受限的大脑区域中。过去十年,在解决与哺乳动物大脑中成体神经发生的几乎各个方面相关的问题方面取得了巨大进展。在这里,我们回顾了我们对成年哺乳动物海马齿状回神经发生以及侧脑室室下区、头侧迁移流到嗅球的神经发生的主要进展。我们重点介绍对干细胞生物学、发育神经生物学、神经可塑性和疾病机制具有重大影响的新兴原理。我们还讨论了与成体神经干细胞及其生态位、潜在调节机制和成体大脑中新生神经元的潜在功能相关的剩余问题。在最新进展的基础上并在新技术的帮助下,成人神经发生领域有望在未来十年实现飞跃发展。
Adult neurogenesis, a process of generating functional neurons from adult neural precursors, occurs throughout life in restricted brain regions in mammals. The past decade has witnessed tremendous progress in addressing questions related to almost every aspect of adult neurogenesis in the mammalian brain. Here we review major advances in our understanding of adult mammalian neurogenesis in the dentate gyrus of the hippocampus and from the subventricular zone of the lateral ventricle, the rostral migratory stream to the olfactory bulb. We highlight emerging principles that have significant implications for stem cell biology, developmental neurobiology, neural plasticity, and disease mechanisms. We also discuss remaining questions related to adult neural stem cells and their niches, underlying regulatory mechanisms and potential functions of newborn neurons in the adult brain. Building upon the recent progress and aided by new technologies, the adult neurogenesis field is poised to leap forward in the next decade.
