1Spatial transcriptomic survey of human embryonic cerebral cortex by single-cell RNA-seq analysis显示文摘人的大脑开发的细胞的复杂性强烈地被调查了,尽管全部人的服的外皮的地区性的描述没基于单个房间的 transcriptome 分析被报导。这里,我们从人的中间怀孕期的胚胎的 22 个大脑区域在超过 4,000 个单个房间上执行了 RNA-seq。我们识别了 29 房间亚簇,它证明在每个区域和脑桥的不同比例显示出星形细胞的特别高的百分比。胚胎的神经原不象成年神经原一样多样,尽管他们在成年人拥有了他们的命运的重要特征。神经原开发是在服的外皮的 unsynchronized,当背面的区域看起来比在这个阶段的腹的区域更成熟。区域特定的基因包括地在每 neuronal 亚簇被识别,并且这些基因的一个大比例是联系的神经疾病。我们的结果介绍区域化的基因表示的一处系统的风景和人的服的外皮的神经原成熟。Xiaoying Fan Ji Dong Suijuan Zhong Yuan Wei Qian Wu Liying Yan Jun Yong Le Sun Xiaoye Wang Yangyu Zhao Wei Wang Jie Yan Xiaoqun Wang Jie Qiao Fuchou Tang 2018Cell Research2018,28,7:11
2Loss of the centrosomal protein Cenpj leads to dysfunction of the hypothalamus and obesity in mice显示文摘Cenpj is a centrosomal protein located at the centrosomes and the base of cilia,it plays essential roles in regulating neurogenesis and cerebral cortex development.Although centrosomal and cilium dysfunction are one of the causes of obesity,insulin resistance,and type 2 diabetes,the role that Cenpj plays in the regulation of body weight remains unclear.Here,we deleted Cenpj by crossing Cenpjflox/flox mice with Nkx2.1-Cre mice.Loss of the centrosomal protein Cenpj in Nkx2.1-expressing cells causes morbid obesity in mice at approximately 4 months of age with expended brain ventricles but no change of brain size.We found that hypothalamic cells exhibited reduced proliferation and increased apoptosis upon Cenpj depletion at the embryonic stages,resulting in a dramatic decrease in the number of Proopiomelanocortin(POMC)neurons and electrophysiological dysfunction of NPY neurons in the arcuate nucleus(ARC)in adults.Furthermore,depletion of Cenpj also reduced the neuronal projection from the ARC to the paraventricular nucleus(PVN),with decreased melanocortin-4 receptors(MC4R)expression in PVN neurons.The study defines the roles that Cenpj plays in regulating hypothalamus development and body weight,providing a foundation for further understanding of the pathological mechanisms of related diseases.Wenyu Ding Changjiang Zhang Baisong Wang Xin Zhou Le Sun Suijuan Zhong Jing Liu Junjing Zhang Xiaoqun Wang Qian Wu 2021Science China(Life Sciences)2021,64,3:1
3A single-cell transcriptome atlas of the aging human and macaque retina显示文摘The human retina is a complex neural tissue that detects light and sends visual information to the brain.However,the molecular and cellular processes that underlie aging primate retina remain unclear.Here,we provide a comprehensive transcriptomic atlas based on 119520 single cells of the foveal and peripheral retina of humans and macaques covering different ages.The molecular features of retinal cells differed between the two species,suggesting distinct regional and species specializations of the human and macaque retinae.In addition,human retinal aging occurred in a region-and cell-type-specific manner.Aging of human retina exhibited a foveal to peripheral gradient.MYO9A-rods and a horizontal cell subtype were greatly reduced in aging retina,indicating their vulnerability to aging.Moreover,we generated a dataset showing the cell-type-and region-specific gene expression associated with 55 types of human retinal disease,which provides a foundation to understanding of the molecular and cellular mechanisms underlying human retinal diseases.Such datasets are valuable to understanding of the molecular characteristics of primate retina,as well as molecular regulation of aging progression and related diseases.Wenyang Yi Yufeng Lu Suijuan Zhong Mei Zhang Le Sun Hao Dong Mengdi Wang Min Wei Haohuan Xie Hongqiang Qu Rongmei Peng Jing Hong Ziqin Yao Yunyun Tong Wei Wang Qiang Ma Zeyuan Liu Yuqian Ma Shouzhen Li Chonghai Yin Jianwei Liu Chao Ma Xiaoqun Wang Qian Wu Tian Xue 2021National Science Review2021,8,4:1
4Decoding the spatiotemporal regulation of transcription factors during human spinal cord development显示文摘The spinal cord is a crucial component of the central nervous system that facilitates sensory processing and motor performance.Despite its importance,the spatiotemporal codes underlying human spinal cord development have remained elusive.In this study,we have introduced an image-based single-cell transcription factor(TF)expression decoding spatial transcriptome method(TF-seqFISH)to investigate the spatial expression and regulation of TFs during human spinal cord development.By combining spatial transcriptomic data from TF-seqFISH and single-cell RNA-sequencing data,we uncovered the spatial distribution of neural progenitor cells characterized by combinatorial TFs along the dorsoventral axis,as well as the molecular and spatial features governing neuronal generation,migration,and differentiation along the mediolateral axis.Notably,we observed a sandwich-like organization of excitatory and inhibitory interneurons transiently appearing in the dorsal horns of the developing human spinal cord.In addition,we integrated data from 10×Visium to identify early and late waves of neurogenesis in the dorsal horn,revealing the formation of laminas in the dorsal horns.Our study also illuminated the spatial differences and molecular cues underlying motor neuron(MN)diversification,and the enrichment of Amyotrophic Lateral Sclerosis(ALS)risk genes in MNs and microglia.Interestingly,we detected disease-associated microglia(DAM)-like microglia groups in the developing human spinal cord,which are predicted to be vulnerable to ALS and engaged in the TYROBP causal network and response to unfolded proteins.These findings provide spatiotemporal transcriptomic resources on the developing human spinal cord and potential strategies for spinal cord injury repair and ALS treatment.Yingchao Shi Luwei Huang Hao Dong Meng Yang Wenyu Ding Xiang Zhou Tian Lu Zeyuan Liu Xin Zhou Mengdi Wang Bo Zeng Yinuo Sun Suijuan Zhong Bosong Wang Wei Wang Chonghai Yin Xiaoqun Wang Qian Wu 2024Cell Research2024,34,3:0
5Ferrodifferentiation regulates neurodevelopment via ROS generation显示文摘Iron is important for life,and iron deficiency impairs development,but whether the iron level regulates neural differentiation remains elusive.In this study,with iron-regulatory proteins(IRPs)knockout embryonic stem cells(ESCs)that showed severe iron deficiency,we found that the Pax6-and Sox2-positive neuronal precursor cells and Tuj1 fibers in IRP1^(-/-)IRP2^(-/-)ESCs were significantly decreased after inducing neural differentiation.Consistently,in vivo study showed that the knockdown of IRP1 in IRP2^(-/-)fetal mice remarkably affected the differentiation of neuronal precursors and the migration of neurons.These findings suggest that low intracellular iron status significantly inhibits neurodifferentiation.When supplementing IRP1^(-/-)IRP2^(-/-)ESCs with iron,these ESCs could differentiate normally.Further investigations revealed that the underlying mechanism was associated with an increase in reactive oxygen species(ROS)production caused by the substantially low level of iron and the downregulation of iron-sulfur cluster protein ISCU,which,in turn,affected the proliferation and differentiation of stem cells.Thus,the appropriate amount of iron is crucial for maintaining normal neural differentiation that is termed ferrodifferentiation.Shiyang Chang Peina Wang Yingying Han Qiang Ma Zeyuan Liu Suijuan Zhong Yufeng Lu Ruiguo Chen Le Sun Qian Wu Guofen Gao Xiaoqun Wang Yan-Zhong Chang 2023Science China(Life Sciences)2023,66,8:0
