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.

Project description:Long non-coding RNAs (lncRNAs) are a diverse category of transcripts with poor conservation and have expanded greatly in primates, particularly in their brain. We identified a lncRNA, which has acquired 16 microRNA response elements (MREs) for miR-143-3p in the Catarrhini branch of primates. This lncRNA termed LncND (neuro-development) gets expressed in neural progenitor cells and then declines in mature neurons. Binding and release of miR-143-3p, by LncND, can control the expression of Notch. Its expression is highest in radial glia cells in the ventricular and outer subventricular zones of human fetal brain. Down-regulation of LncND in neuroblastoma cells reduced cell proliferation and induced neuronal differentiation, an effect phenocopied by miR-143-3p over-expression and supported by RNA-seq analysis. These findings support a role for LncND in miRNA-mediated regulation of Notch signaling in the expansion of the neural progenitor pool of primates and hence contributing to the rapid growth of the cerebral cortex. SHSY5Y cells treated either with miR-143-3p mimic or 100 nM of siRNA specific for LncND were sequenced on NextSeq500 platform. Scrambled siRNA or miRNA sequences were used as a negative control.

Project description:<p>Non-coding regions comprise most of the human genome and harbor a significant fraction of risk alleles for neuropsychiatric diseases, yet their functions remain poorly defined. We created a high-resolution map of non-coding elements involved in human cortical neurogenesis by contrasting chromatin accessibility and gene expression in the germinal zone and cortical plate of the developing cerebral cortex. To obtain a high resolution depiction of chromatin structure and gene expression in developing human fetal cortex, we dissected the post-conception week (PCW) 15-17 human neocortex into two major anatomical divisions to distinguish between proliferating neural progenitors and post mitotic neurons: (1) GZ: the neural progenitor-enriched region encompassing the ventricular zone (VZ), subventricular zone (SVZ), and intermediate zone (IZ) and (2) CP: the neuron-enriched region containing the subplate (SP), cortical plate (CP), and marginal zone (MZ). Tissues were obtained from three independent donors and three to four technical replicates from each tissue were processed for ATAC-seq to define the landscape of accessible chromatin and RNA-seq for genome-wide gene expression profiling.</p>

Cerebral organoids were generated as in Lancaster et al. (Lancaster and Knoblich, 2014). Organoids were dissociated into single cells and captured on C1 Single-Cell Auto Prep Integrated Fluidic Circuit (IFC) (Fluidigm). The RNA extraction and amplification was performed on the chip as described by the manufacturer. We captured 68 single-cells on a C1 Single-Cell Auto Prep System (Fluidigm) and sequenced the RNA on a NextSeq500 System (Illumina) (Pollen et al., 2014). Out of 68 cells, we obtained 60 high quality cells.

Project description:We have developed spontaneous genetically engineered GBM mouse models from two distinct cells of origin: subventricular zone neural stem cells (SVZ; Nestin-creERT2) and oligodendrocyte lineage progenitor cells (OPC; NG2-creERTM). These tumors are biologically separable and are reflective of their lineage of origin.
