Mouse ESC-derived NSPCs NFIA OE (GE)

ABSTRACT: Since the NFI transcription factors have been shown to be key regulators of gliogenesis, we utilized this pathway to identify miRNAs involved in the regulation of the neurogenesis-to-gliogenesis switch by neural stem/progenitor cells (NSPCs). We focused on miRNAs with expression levels that were differentially regulated downstream of NFIA, and established a mouse embryonic stem cell (ESC) line that expresses NFIA in a doxycycline (Dox)-dependent manner. NFIA-overexpressing (OE) and control NSPCs (neurospheres) derived from ESCs were purified from their mixed cultures (primary neursphsres (PNs) or secondary neurospheres (SNs) ) by fluorescence activated cell sorting and subjected to the gene expression microrray analysis.

miR-153 overexpressing NSPCs derived from mouse ES cells

Project description:Mammalian neural stem/progenitor cells (NSPCs) sequentially generate neurons and glia during central nervous system (CNS) development. Several transcription factors and microRNAs (miRNAs) are involved in the temporal regulation of NSPC differentiation. miRNA-153 (miR-153) as a modulator of NSPC specification. Overexpression (OE) of miR-153 delayed the onset of astrogliogenesis and maintained NSPCs in an undifferentiated state in vitro. miR-153-OE and control NSPCs (tertiary neurospheres (TNs) derived from mouse ES Cells via embryoid body formation) subjected to the gene expression microarray analysis.

Common regulatory targets of NFIA, NFIX and NFIB during postnatal cerebellar development

Project description:Transcriptional regulation plays a central role in controlling neural stem and progenitor cell proliferation and differentiation during neurogenesis. For instance, transcription factors from the nuclear factor I (NFI) family have been shown to co-ordinate neural stem and progenitor cell differentiation within multiple regions of the embryonic nervous system, including the neocortex, hippocampus, spinal cord and cerebellum. Knockout of individual Nfi genes culminates in similar phenotypes, suggestive of common target genes for these transcription factors. However, whether or not the NFI family regulates common suites of genes remains poorly defined. Here, we use granule neuron precursors (GNPs) of the postnatal murine cerebellum as a model system to analyse regulatory targets of three members of the NFI family: NFIA, NFIB and NFIX. By integrating transcriptomic profiling (RNA-seq) of Nfia- and Nfix-deficient GNPs with epigenomic profiling (ChIP-seq against NFIA, NFIB and NFIX, and DNase I hypersensitivity assays), we reveal that these transcription factors share a large set of potential transcriptional targets, suggestive of complementary roles for these NFI family members in promoting neural development.

Expression data from proliferating and quiescent adult hippocampal neural stem and progenitor cells

Project description:We have characterized the transcriptome of adult rat hippocampal neural stem and progenitor cell (NSPC) cultures. The NSPCs cultures can be reversibly arrested by the quiescence-promoting signal BMP4. We provide expression data from NSPCs grown as neurospheres for 4 days in vitro in the presence of FGF2 (proliferating NSPCs) or FGF2+BMP4 (quiescent NSPCs) showing that entry into quiescence involves major changes in the transcriptional profile of the cells.

Control of neurogenic competence in mammalian hypothalamic tanycytes [RNA-seq]

Project description:Hypothalamic tanycytes, radial glial cells that share many features with neuronal progenitors, can generate small numbers of neurons in the postnatal hypothalamus, but the identity of these neurons and the molecular mechanisms that control tanycyte-derived neurogenesis are unknown. We report that tanycyte-specific disruption of the NFI family of transcription factors (Nfia/b/x) stimulates proliferation and tanycyte-derived neurogenesis. Single-cell RNA- and ATAC-Seq analysis reveals that NFI factors repress Shh and Wnt signaling in tanycytes, and small molecule inhibition of these pathways blocks proliferation and tanycyte-derived neurogenesis in Nfia/b/x-deficient mice. We show that Nfia/b/x-deficient tanycytes give rise to multiple mediobasal hypothalamic neuronal subtypes that can mature, integrate into hypothalamic circuitry, and selectively respond to changes in internal states. These findings identify molecular mechanisms controlling tanycyte-derived neurogenesis that can potentially be targeted to selectively remodel hypothalamic neural circuitry controlling homeostatic physiological processes.
