(Submitter supplied) Our brains accommodate a largely folded cerebral cortex that associates to our advanced brain functions. Several theories have been proposed to explain the cortical folding process, reasoning the mechanical forces as neuronal tension in underlying layers, cellular expansion and glial progenitor’s diversity in the OSVZ; but the mechanistic insights and underlying genomics changes causing the appearance of cortical folds is still illusive. more...

(Submitter supplied) Cortical neurogenesis follows a simple lineage: apical Radial Glia Cells (RGC) generate basal progenitors, and these produce neurons. How this occurs in species with expanded germinal zones and a folded cortex, like human, remains unclear. We used single-cell RNA sequencing from individual cortical germinal zones in ferret, and barcoded lineage tracking, to determine the molecular diversity of progenitor cells and their lineages. more...

(Submitter supplied) Diversity of cortical radial glia cells (RGCs) and their complex relationships to generate neurons in species with expanded germinal zones and a folded cortex, remains unclear. We used TrackerSeq, a technique that integrates DNA barcodes into the genome of electroporated RGCs, to identify the distinct cell lineages that shape ferret cortex.

(Submitter supplied) Diversity of cortical radial glia cells (RGCs) and their complex relationships to generate neurons in species with expanded germinal zones and a folded cortex, remains unclear. We used single-cell RNA sequencing (scRNA-seq) of microdissected cortical germinal layers (ventricular zone (VZ) and outer subventricular zone (OSVZ)), from two cortical regions (splenial gyrus (SG) and neighboring lateral sulcus (LS)) at two critical time points for ferret cortex development (embryonic day (E) 34 and postnatal day (P) 1) to distinguish the molecular diversity of progenitors and newborn neurons, and study their transcriptomic trajectories.

(Submitter supplied) Gyrencephalic species develop folds in the cerebral cortex in a stereotypic manner, but the genetic mechanisms underlying this unique patterning process are unknown. We present a large-scale transcriptomic analysis of individual germinal layers in the developing cortex of the gyrencephalic ferret, comparing between regions prospective of fold and fissure. We find unique transcriptional signatures in each germinal compartment, indicating that thousands of genes are differentially expressed between regions, including ~80% of genes mutated in human cortical malformations. more...

(Submitter supplied) Conditional deletion of Geminin from the entire hematopoietic compartment using Vav1:iCre mice led to defective hematopoiesis/dyserythropoiesis in E15.5 mouse embryos. The present data set includes data from lineage-negative cells isolated from homogenized livers that were dissected from E15.5.dpc embryos. The two conditions compared were wild-type versus Geminin-KO Lin- cells. The cells were collected from littermates.

(Submitter supplied) As described in our paper "Aspm knockout ferret reveals an evolutionary mechanism governing cerebral cortical size" (Johnson et al., Nature 2018), we used the standard Drop-seq method and analysis of Macosko et al. (2015) to capture, sequence, and analyze mRNA from single cells from Aspm wild-type, heterozygous, and knock-out littermate ferrets at embryonic day 35. Bulk reference samples were processed using standard Illumina mRNA-seq library prep and sequencing protocols, and the samples were described previously (Johnson, Wang et al., Nature Neurosci 2015)

(Submitter supplied) Increased cortical size is essential to the enhanced intellectual capacity of primates during mammalian evolution. The mechanisms that control cortical size are largely unknown. Here, we show that mammalian BAF170, a subunit of the chromatin remodeling complex mSWI/SNF, is an intrinsic factor that controls cortical size. We find that the conditional deletion of BAF170 promotes indirect neurogenesis by increasing the pool of intermediate progenitors (IPs) and results in an enlarged cortex, whereas cortex-specific BAF170 over-expression results an opposing phenotype. more...

(Submitter supplied) Although technological advances now allow increased tumor profiling, a detailed understanding of the mechanisms leading to the development of different cancers remains elusive. Our approach towards understanding the molecular events that lead to cancer is to characterize changes in transcriptional regulatory networks between normal and tumor tissue. Because enhancer activity is thought to be critical in regulating cell fate decisions, we have focused our studies on distal regulatory elements and transcription factors that bind to these elements. more...

(Submitter supplied) Ptf1a has been shown to be necessary for determining an inhibitory interneuronal fate in many regions of the nervous system. In this study, we aim to investigate the sufficiency of Ptf1a to cell-autonomously promote a specific neuronal identity by misexpressing it in developing excitatory cortical pyramidal cells and studying its impact on pyramidal cell features, such as its gene expression profile. more...

(Submitter supplied) Germ cell specification is accompanied by epigenetic remodeling, the scale and specificity of which are unclear. Here, we quantitatively delineate chromatin dynamics during induction of mouse embryonic stem cells (ESCs) to epiblast-like cells (EpiLCs) and from there into primordial germ cell-like cells (PGCLCs), revealing large-scale reorganization of chromatin signatures including H3K27me3 and H3K9me2 patterns. more...

(Submitter supplied) We re-analyzed gene expression in the primordial germ cell (PGC) specification pathway in vitro, by using previously deposited microarray data. The germ cell lineage produces either spermatozoa or oocytes and, by their fusion, creates zygotes with full developmental potential, thereby perpetuating and diversifying organisms' genetic as well as epigenetic information across generations. In mice, PGCs are specified in the most posterior part of epiblast (monolayer epitherium-like cells, from which the whole embryonic part of conceptus will be derived) around embryonic day (E) 6.25 by a cytokine BMP4. more...

(Submitter supplied) The human cerebral cortex depends for its normal development and size on a precisely controlled balance between self-renewal and differentiation of diverse neural progenitor cells. Specialized progenitors that are common in humans, but virtually absent in rodents, called ‘outer radial glia’ (ORG), have been suggested to be crucial to the evolutionary expansion of the human cortex. We combined cell type-specific sorting with transcriptome-wide RNA-sequencing to identify genes enriched in human ORG, including targets of the transcription factor Neurogenin, and previously uncharacterized, evolutionarily dynamic, long noncoding RNAs. more...

(Submitter supplied) A small subgroup of embryonic stem cells (ESCs) exhibit molecular features similar to those of 2-cell (2C) embryos. These so-called 2C-like cells display highly relaxed chromatin architecture and expanded developmental potential. However, it remains elusive whether 2C-like cells and 2-cell embryos share similar epigenetic features. Here, we map the genome-wide profiles of histone H3K4me3 and H3K27me3 in 2C-like cells. more...

Combinatorial interactions of transcription factors (TFs), regulatory elements (REs), and chromatin are thought to precisely regulate gene expression. In the medial ganglionic eminence (MGE), the NKX2-1 TF controls regional identity and, with LHX6, is necessary to specify pallidal projection neurons and forebrain interneurons. more...
