Bulk RNA-seq of mouse neural stem and progenitor cells (NSPC) derived from embryonic stem cells, with allele-specific deletions of a Sox2 enhancer cluster

ABSTRACT: We have generated RNA-sequencing datasets of the regulome of mouse neural stem and progenitor cells derived from embryonic stem cells, with allele-specific deletions of Sox2 enhancer cluster regions. RNA-seq experiments were conducted to evaluate the regulatory function of Sox2 candidate enhancers in neural stem and progenitor cells.

Bulk ATAC-seq of mouse neural stem and progenitor cells (NSPC) derived from embryonic stem cells, with biallelic Sox2 enhancer cluster deletions

Project description:We have generated ATAC-sequencing datasets of the regulome of mouse neural stem and progenitor cells derived from embryonic stem cells, with allele-specific deletions of Sox2 enhancer cluster regions. ATAC-seq experiments were conducted to evaluate the alterations in chromatin accessibility at candidate regulatory elements genome-wide in neural stem and progenitor cells with Sox2 enhancer loss-of-function.

Prospective Identification, Isolation, and Profiling of a Telomerase-Expressing Subpopulation of Human Neural Stem Cells, using sox2 Enhancer-Directed Fluorescence-Activated Cell Sorting

Project description:Sox2 is expressed by neural stem and progenitor cells, and a sox2 enhancer identifies these cells in the forebrains of both fetal and adult transgenic mouse reporters. We found that an adenovirus encoding EGFP placed under the regulatory control of a 0.4 kb sox2 core enhancer selectively identified multipotential and self-renewing neural progenitor cells in dissociates of human fetal forebrain. Gene expression analysis of E/sox2:EGFP-sorted neural progenitor cells, normalized to the unsorted forebrain dissociates from which they derived, revealed marked overexpression of genes within the notch and wnt pathways, and identified multiple elements of each pathway that appear selective to human neural progenitors. We used adenoviral E/sox2:EGFP to transduce dissociates of the second trimester human ventricular zone (VZ)/ subventricular zone (SVZ), followed by EGFP-directed fluorescence-activated cell sorting (FACS). The sox2 isolates and unsorted controls from different gestational ages (16-19 wks, n=4) were then subject to RNA extraction and hybridization on Affymetrix microarrays.

A Sox2 distal enhancer cluster regulates embryonic stem cell differentiation potential

Project description:We report the effect on genome-wide gene expression after deletion of an enhancer region downstream of Sox2 in F1 ES cells. The Sox2 transcription factor must be robustly transcribed in embryonic stem (ES) cells to maintain pluripotency. Reporter assays reveal novel enhancers, including two enhancers over 100 kb downstream (SRR107 and SRR111) which, through the formation of chromatin loops, localise to the Sox2 promoter in ES cells. Using CRISPR/Cas9 we deleted a region containing these two enhancers, which we term the Sox2 control region (SCR). This deletion revealed that the SCR is required for Sox2 transcription in ES cells. Furthermore, homozygous deletion of this distal Sox2 control region (SCR) caused significant reduction in Sox2 mRNA and protein levels, loss of ES cell colony morphology, genome-wide changes in gene expression and impaired neuroectodermal formation upon spontaneous differentiation to embryoid bodies. Together these data identify a distal control region essential for Sox2 transcription in ES cells. Examination of PolA+ RNA after heterozygous and homozygous enhancer deletion in F1 ES cells (M. musculus129 x M. castaneus).

Sox2 ChIP-seq in hindbrain and spinal cord neural progenitors differentiated from mouse embryonic stem cells

Project description:Sox2 is a key determinant of neural cell identity, expressed in neural progenitors from anterior to posterior levels. We asked if the occupancy of this factor changes in neural progenitors with different axial identities. To this end, we performed the directed differentiation of mouse embryonic stem cells to generate neural progenitors in vitro with either hindbrain or spinal cord identity. We then performed Sox2 ChIP-seq (antibody SC-17320X), to assess the difference in Sox2 occupancy at these two different axial levels. This revealed that the genome-wide occupancy of Sox2 in neural progenitors changes depending on axial identity.

Linc1548 promotes the transition of epiblast stem cells into neural progenitors by engaging OCT6 and SOX2

Project description:The transition of embryonic stem cells from the epiblast stem cells (EpiSCs) to neural progenitor cells (NPCs), name as the neural induction process, is crucial for cell fate determination of neural differentiation. However, the mechanism of this transition is unclear. Here, we identified a long non-coding RNA (linc1548) as a critical regulator of neural differentiation of mouse embryonic stem cells (mESCs). Knockout of linc1548 did not affect the conversion of mESCs to EpiSCs, but delayed the transition from EpiSCs to NPCs. Moreover, linc1548 interacts with the transcription factors OCT6 and SOX2 forming an RNA-protein complex to regulate the transition from EpiSCs to NPCs. Finally, we showed that Zfp521 is an important target gene of this RNA-protein complex regulating neural differentiation. Our findings prove how the intrinsic transcription complex mediated by a lncRNA linc1548 and can better understand the intrinsic mechanism of neural fate determination.
