(Submitter supplied) In vitro cortex generated from embryonic stem cells (ESCs) is a model system to investigate corticogenesis and a promising tool for cortical therapy. A fundamental question that has implications for understanding corticogenesis and for using stem cells therapeutically is to determine whether in vitro cortex reproduces some fine-tuned epigenetic modifications that are important for corticogenesis and function in vivo such as parent-of-origin dependent DNA methylation and expression of imprinted genes (IGs). more...

(Submitter supplied) In vitro differentiation of embryonic stem cells (ESC) provides models that reproduce in vivo development and cells for therapy. Whether the epigenetic signatures that are crucial for brain development and function and that are sensitive to in vitro culture are similar between native brain tissues and their artificial counterpart generated from ESC is largely unknown. Here, using RNA-seq we have compared the parental origin-dependent expression of imprinted genes (IGs), a model of epigenetic regulation, in cerebral cortex generated either in vivo, or from ESCs using in vitro corticogenesis, a model that reproduces the landmarks of in vivo corticogenesis. more...

(Submitter supplied) Mechanisms establishing higher-order chromosome structures and their roles in gene regulation are elusive. We analyzed chromosome architecture during nematode X-chromosome dosage compensation, which represses transcription via a dosage-compensation condensin complex (DCC) that binds hermaphrodite Xs and establishes megabase-size topologically associating domains (TADs). We show that DCC binding at high-occupancy sites (rex sites) defines eight TAD boundary locations. more...

(Submitter supplied) Genomic imprinting is an epigenetic mechanism that results in parent-of-origin monoallelic expression of specific genes, which precludes uniparental development and underlies various diseases. Here, we explored molecular and developmental aspects of imprinting in humans by generating exclusively paternal human androgenetic embryonic stem cells (aESCs) and comparing them with exclusively maternal parthenogenetic ESCs (pESCs) and bi-parental ESCs, establishing a pluripotent cell system of distinct parental backgrounds. more...

(Submitter supplied) The cyclin-dependent kinase inhibitor p57KIP2 is encoded by the imprinted Cdkn1c locus, exhibits maternal expression, and is essential for cerebral cortex development. How Cdkn1c regulates corticogenesis is however not clear. To this end we employ Mosaic Analysis with Double Markers (MADM) technology to genetically dissect Cdkn1c gene function in corticogenesis at single cell resolution. We find that the previously described growth-inhibitory Cdkn1c function is a non-cell-autonomous one, acting on the whole organism. more...

(Submitter supplied) Genomic imprinting, resulting in parent-of-origin specific gene expression, plays a critical role in mammalian development. Here, we perform allele-specific RNA-Seq on isogenic B6D2F1 mice to assay imprinted genes in tissues from early embryonic stages and in pluripotent cell lines. For the cell lines, we include embryonic stem cells (ESCs) and epiblast stem cells (EpiSCs) derived from fertilized embryos or from embryos obtained after nuclear transfer (NT), as well as B6D2F1 ESCs and EpiSCs derived after parthenogenetic activation (PGA). more...

(Submitter supplied) During early mammalian development transient pools of pluripotent cells emerge that can be immortalised upon stem cell derivation. The pluripotent state, "naïve" or "primed", depends on the embryonic stage and derivation conditions used. Here we analyse the temporal gene expression patterns of mouse, cattle and porcine embryos at stages that harbour different types of pluripotent cells. We document conserved and divergent traits in gene expression, and identify predictor genes shared across the species that are associated with pluripotent states in vivo and in vitro Amongst these are the pluripotency-linked genes Klf4 and Lin28b The novel genes discovered include naïve- (Spic, Scpep1 and Gjb5) and primed-associated (Sema6a and Jakmip2) genes as well as naïve-to primed transition genes (Dusp6 and Trip6). more...

(Submitter supplied) ZFP57 interacts with the germline-derived differentially methylated regions (DMRs) of imprinted genes, and is required to maintain DMR methylation in mouse embryonic stem cells (ESCs). Although DNA methylation has a key role in maintaining genomic imprinting, several imprinted genes are controlled by different mechanisms, and a comprehensive study of the relationship between DMR methylation and imprinted gene expression is lacking. more...

(Submitter supplied) One possible mechanism leading to the apparent polymorphic placenta-specific DMRs would be the failure to maintain allelic methylation during gestation. For a temporal comparison, we performed methylation profiling on first trimester chorionic villus sampling (CVS) and compared it with corresponding samples at term. This revealed that DNA methylation level at placenta-specific DMRs is highly stable between the two points. more...

(Submitter supplied) The placenta has a critical role in fetal growth, with many key functions regulated by genomic imprinting. With the recent description of polymorphic placenta-specific imprinting, the molecular mechanisms leading to this curious epigenetic phenomenon are unknown, as is their involvement in pregnancies complications. Profiling ubiquitous and placenta-specific imprinted differentially methylated regions (DMRs) exposed isolated aberrant methylation at ubiquitous DMRs as well as abundant hypomethylation at placenta-specific DMRs. more...

(Submitter supplied) Purpose: In this study we investigated the molecular role of cytosine modification in the developing cortex of mice. To this aim we isolated thee linage related cell populations of the developing cortex and mapped both, 5mC as well as 5hmC on a genome-wide scale. Furthermore we established a system to site-specifcally demethylate DNA by using a dCas9-Tet1 fusion protein. Methods: Neuronal stem cells (Btg2-/Tubb3-), neurogenic progenitors (Btg2+/Tubb3-) and neurons (Tubb3+) were isolated from E14.5 Btg2-RFP/Tubb3-GFP double heterozygous mouse embryos (Aprea et al. more...
