Physical interactions between Gsx2 and Ascl1 balance progenitor expansion versus neurogenesis in the mouse lateral ganglionic eminence

Project description:These findings suggest that physical interactions between Gsx2 and Ascl1 limit Ascl1:Ascl1 and Ascl1:Tcf3 interactions, and thereby inhibit Ascl1-dependennt neurogenesis and allow for progenitor expansion within the LGE.

Bulk RNA-seq of the human fetal neocortex, lateral ganglionic eminence and medial ganglionic eminence at 7, 9, 11 and 20 post-conceptional weeks

Project description:Deep transcriptional profiling of the human neocortex, lateral ganglionic eminence (LGE) and medial ganglionic eminences (MGE), from 7 to 20 post-conceptional weeks (pcw), for de novo lincRNAs discovery and to establish a unique coding and non-coding gene signature for the three different regions.

Comparative expression of embryonic medial- and lateral/caudal-ganglionic eminence cells migrating in the mouse cerebral cortex

Project description:Cortical interneurons originate in the medial and caudal ganglionic eminence and migrate into the cortex during embryogenesis. We purified cells migrating within the cortex at different embryonic stages and compared their transcriptome to identify transcriptional programmes underlying distinct cortical interneuron fates.

Expression data from purified medial ganglionic eminence (MGE) interneurons, 3 biological replicates

Project description:During development, newborn interneurons migrate throughout the embryonic brain. Here, we provide evidence that these interneurons act in a paracrine fashion to regulate developmental oligodendrocyte formation. Specifically, we show that medial ganglionic eminence (MGE) interneurons secrete factors that promote genesis of oligodendrocytes from glially-biased cortical precursors in culture. Moreover, when MGE interneurons are genetically ablated in vivo prior to their migration, this causes a deficit in cortical oligodendrogenesis. Modeling of the interneuron-precursor paracrine interaction using transcriptome data identifies the cytokine fractalkine as responsible for the pro-oligodendrocyte effect in culture. This paracrine interaction is important in vivo, since knockdown of the fractalkine receptor CX3CR1 in embryonic cortical precursors, or constitutive knockout of CX3CR1 causes decreased numbers of oligodendrocyte progenitor cells (OPCs) and oligodendrocytes in the postnatal cortex. Thus, in addition to their role in regulating neuronal excitability, interneurons act in a paracrine fashion to promote the developmental genesis of oligodendrocytes. We used microarrays to generate a list of expressed genes in purified medial ganglionic eminence (MGE) interneurons

ChIP-seq for TCF4 in human medial ganglionic eminence-like organoids (hMGEOs) derived from ihtc-03 cell line.

Project description:To depict the gene regulatory network of TCF4 in interneuron development, We performed chromatin immunoprecipitation-sequencing (ChIP seq) on human medial ganglionic eminence-like organoids (hMGEOs) to identify genome-wide TCF4 binding sites. This study provides compelling evidence to support the biological rationale linking TCF4 to the developing cortical interneuron.

Comparison between mouse ES/iPS derived neurosphere and mouse primary culture of neurospheres obtained from fetal mouse ganglionic eminence

Project description:Recent reports have emphasized the pitfalls of iPSC technology including the potential for immunogenicity of transplanted cells. It is serious safety-related concern for iPSC-based cell therapy. However, preclinical data supporting the safety and efficacy of iPSCs are also accumulating. To address the concern of immunogenicity of ESCs/iPSCs or ESCs/iPSCs-derived neurospheres, global gene expression profiles were compared between undifferentiated mouse ESCs (EB3 line), mouse iPSCs (38C2 line), and ESC/iPSC-derived neurosphere and mouse primary culture of neurosphere obtained from fetal mouse ganglionic eminence. Mouse adult sklin fibroblast was used as a control. We used affymetrix microarrays to compare the global gene expression of neurospheres prepared several origins. Keywords: Expression profiling by array RNA extracted from neurospheres was hybridized to Affymetrix microarrays.
