Single-cell transcriptome profiling of radial glia cells in zebrafish adult telencephalon in response to traumatic brain injury

Project description:In zebrafish brain, radial glia cells (RG) show a remarkable ability to regenerate damaged neural tissue by reentering cell proliferation and produce neural precursors. To understand how RG respond to brain damage and initiate the regenerative response, we applied single-cell transcriptome analysis to RG in zebrafish adult telencephalon.

Cellular and Transcriptomic Analyses Identify the Source and Lineage of Regenerated Neurons in the Adult Zebrafish Telencephalon following Blunt-Force Traumatic Brain Injury

Project description:Traumatic brain injuries (TBIs) represent a large global disease burden and can result in several short- and long-term deficits. Treatment for TBIs are limited, however stem cell therapies involving either transplantation of exogenous stem cells or stimulation of endogenous stem cells have been proposed. These approaches possess issues with survival and differentiation of stem/progenitor cells, which highlights the need to elucidate mechanisms necessary for complete regeneration. Zebrafish exhibit a robust neuronal regenerative capacity following damage in various parts of the central nervous system. In this study, we use a modified blunt-force TBI (bfTBI) model, the most common type of TBI seen in the human population, to damage the adult zebrafish telencephalon and examine cellular and molecular consequences. This model induces a variety of TBI-related phenotypes across different injury severities, which mimic the pathologies observed following bfTBI in humans. Additionally, we show that after bfTBI, cells in the zebrafish telencephalon, including radial glia (RGC), non-glial neural progenitors (NPs), and neuroblasts, proliferate and differentiate into various neural cell types. We performed a snRNA-Seq analysis of the damaged and regenerating telencephalon, which revealed heterogeneity among the progenitor cells. Further, the snRNA-Seq demonstrated that quiescent radial glia became activated upon injury and yielded neural progenitor cells. To functionally assess how the regenerative process is regulated, we knocked down the expression of PdgfrB and demonstrated that it played a role in maintaining RGC quiescence. Collectively, this study provides a foundation for future studies of neuronal regeneration in the adult zebrafish telencephalon following a bfTBI.

Single cell sequencing of radial glia progeny reveals diversity of newborn neurons in the adult zebrafish brain

Project description:Zebrafish display widespread and pronounced adult neurogenesis, which is fundamental for their regeneration capability after central nervous system injury. However, the cellular identity and the biological properties of adult newborn neurons are elusive for most brain areas. Here, we used short-term lineage tracing of radial glia progeny to prospectively isolate newborn neurons from the her4.1+ radial glia lineage in the homeostatic adult forebrain. Transcriptome analysis of radial glia, newborn neurons and mature neurons using single cell sequencing identified distinct transcriptional profiles including novel markers for each population. Specifically, we detected 2 separate newborn neuron types, which showed diversity of cell fate commitment and location. Further analyses showed homology of these cell types to neurogenic cells in the mammalian brain, identified neurogenic commitment in proliferating radial glia and indicated that glutamatergic projection neurons fate are generated in the adult zebrafish telecephalon. Thus, we prospectively isolated adult newborn neurons from the adult zebrafish forebrain, identified markers for newborn and mature neurons in the adult brain, revealed intrinsic heterogeneity among adult newborn neurons and their homology to mammalian adult neurogenic cell types.

Transcription profiling of mouse functionally distinct radial glial subsets

Project description:Since the discovery of radial glia as the source of neurons, their heterogeneity in regard to neurogenesis has been described by clonal and time-lapse analysis in vitro. However, the molecular determinants specifying neurogenic radial glia differently from radial glia that mostly self-renew remain ill-defined. Here, we isolated two radial glial subsets that co-exist at mid-neurogenesis in the developing cerebral cortex and their immediate progeny. While one subset generates neurons directly, the other is largely non-neurogenic but also gives rise to Tbr2-positive basal precursors, thereby contributing indirectly to neurogenesis. Isolation of ; these distinct radial glia subtypes allowed determining interesting differences in their transcriptome. These transcriptomes were also strikingly different from the transcriptome of radial glia isolated at the end of neurogenesis. This analysis therefore identifies, for the first time, the lineage origin of basal progenitors and the molecular differences of this lineage in comparison to directly neurogenic and gliogenic radial glia.

Generation of cellular diversity through temporal patterning of radial glia during mouse corticogenesis

Project description:Neural cell type diversity arises from both spatial and temporal patterning of neural stem cells. Although spatial patterning mechanisms have been extensively studied, temporal patterning mechanisms remain relatively unexplored. In this study, we addressed generation of diverse neural cell types through lineage progression of mouse cortical radial glia. The time series scRNA-seq and snATAC-seq of mouse cortical development revealed that radial glia temporally transitioned from neurogenesis to gliogenesis. During gliogenic stages, various cell types were generated simultaneously along multidirectional lineage trajectories. We established comprehensive molecular maps for cortical lineage commitment and cellular diversification. The transcriptome and epigenome of cortical radial glia exhibit temporal dynamics, as revealed by scRNA-seq and snATAC-seq. Lhx2, a transcription factor with temporal dynamic chromatin binding activities, was identified as a key regulator of the neurogenesis-to-gliogenesis transition. It maintains neurogenic competence by establishing the active epigenetic state of its target genes.

Radial glia require PDGFD/PDGFRB signaling in human but not mouse neocortex

Project description:Analysis of gene expression over serial 150um sections of a single gestational week 14.5 human neocortical specimen. The hypothesis tested with this dataset was that a transcriptional signature of radial glia (neural stem cells) could be isolated via unsupervised gene coexpression analysis due to variation in the abundance of this cell type from section to section. This dataset is the first of its kind generated using this method (Gene Coexpression Analysis of Serial Sections, or GCASS).

Astroblastomas exhibit radial glia stem cell lineages and differential expression of imprinted and X-inactivation escape genes.

Project description:Astroblastoma (AB) is an unusual brain tumor of unknown origin. We performed an integrated clinicogenomic analysis of 36 AB-like tumors. Lesions with MN1-BEND2 fusions demonstrated decreased promoter methylation and increased expression of IGF2-H19 and DLK1-DIO3 imprinted region genes. They also relatively overexpressed genes highly expressed during fetal brain development prior to 25 post-conception weeks (pcw), including genes enriched in ventricular zone radial glia (vRG), and generally presented in young children. Other tumors highly expressed MAP kinase pathway, PI3K pathway and X-inactivation escape genes. These and a third group of tumors tended to occur in young adults and showed enriched expression of outer radial glia (oRG) and truncated radial glia (tRG) genes, and genes highly expressed after 25 pcw. Many of the latter are involved in axonal migration or synaptic plasticity and are implicated in autism, schizophrenia and other cognitive disorders. Findings suggest that AB-like tumors arise in the context of epigenetic and genetic changes in neural progenitors during fetal and later brain development: early ependymal tumors with MN1-BEND2 fusions (EET-MN1) from vRG-derived progenitor cells, and MAPK/PI3K and classic astroblastomas from oRG- and tRG-derived progenitors, respectively. Lastly, we found that like EET-MN1, immature ependymal cells express IGF2 and may represent an important source of this growth factor in the fetal lateral ventricular zone neural stem cell niche.
