(Submitter supplied) Trophoblast stem cells (TSCs) are derived from the trophoectoderm of blastocysts and maintain ability to self-renewal and differentiation. TSC is a good model to research placenta development in vitro. It will contribute to understanding and improving cloned placentomegaly to compare the transcription and methylation between cloned and natural fertilized embryos throughout TSC derivation process. In the present study, we used SCNT (NT) and SCNT with HDACi treatment (SNT) as cloned groups and natural fertilized (NF) embryos to derive TSCs and chosed 5-time points to peform RNA-seq and RRBS. more...

(Submitter supplied) Trophoblast stem cells (TSCs) are derived from the trophoectoderm of a blastocyst and can maintain self-renewal in vitro. Meanwhile, essential insights into the molecular mechanisms controlling placental developmental could be gained by using TSCs that can differentiate into the various placental trophoblast cell types in vitro. Esrrb is a transcription factor with pivotal roles in maintaining TSCs’ self-renewal, but the exact transcriptional networks that Esrrb involved in TSCs are largely unknown. more...

(Submitter supplied) The human genome contains approximately 27,700 CpG islands (CGIs). Most are associated with promoters and their DNA is nearly always unmethylated. By contrast, CGIs lying within the bodies of genes usually become methylated during differentiation and development. CGIs also normally become methylated at X-inactivated and imprinted genes and abnormally methylated in genome rearrangements and in malignancy. more...

(Submitter supplied) Cells of the trophoblast lineage constitute the major part of placental tissues in higher mammals. Recent derivation of human trophoblast stem cells (TSC) from placental cytotrophoblasts (CT) and from blastocyst opens new opportunities for studying development and function of human placenta. Here we report that inhibition of TGF pathway leads to direct and robust conversion of primed human pluripotent stem cells into TSC. more...

(Submitter supplied) Orchestrated actions of tissue-specific enhancers and transcription factors (TFs) govern the development of the placenta which is an essential organ to support the growth of the fetus during pregnancy. However, human trophoblast stem cells (TSCs)-specific enhancers, TFs, and the mechanisms by which TFs modulate placental development are poorly understood. Here we investigated enhancers, super-enhancers (SE), SE-associated genes in human TSC using RNA-seq and ChIP-seq to interrogate the roles of SE-TFs in human TSCs.

(Submitter supplied) Trophoblast stem (TS) cells are in vitro equivalents to the precursor cells of the placenta. In mice, TS cells can be derived either from polar trophectoderm (TE) of blastocyst outgrowths or from postimplantation extraembryonic ectoderm (ExE), originating from polar TE. Since their first successful derivation in 1998 TS cells have been cultured in serum-rich medium in the presence of fibroblast growth factor 4 (FGF4), the cofactor heparin and embryonic fibroblast conditioned medium. more...

(Submitter supplied) Epigenetic modification plays important roles in plant and animal development. DNA methylation can impact the transposable element (TE) silencing, gene imprinting and regulate gene expression.Through a genome-wide analysis, DNA methylation peaks were respectively characterized and mapped in maize embryo and endosperm genome. Distinct methylation level across maize embryo and endosperm was observed. The maize embryo genome contained more DNA methylation peaks than endosperm. However, the endosperm chloroplast genome contained more DNA methylation peaks to compare with the embryo chloroplast genome. DNA methylation regions were characterized and mapped in genome. More CG island (CGI) shore are methylated than CGI in maize suggested that DNA methylation level is not positively correlated with CpG density. The DNA methylation occurred more frequently in the promoter sequence and transcriptional termination region (TTR) than other regions of the genes. The result showed that 99% TEs we characterized are methylated in maize embryo, but some (34.8%) of them are not methylated in endosperm. Maize embryo and endosperm exhibit distinct pattern/level of methylation. The most differentially methylated two regions between embryo and endosperm are High CpG content promoters (HCPs) and high CpG content TTRs (HCTTRs). DNA methylation peaks distinction of mitochondria and chloroplast DNA were less than the nucleus DNA. Our results indicated that DNA methylation is associated with the gene silencing or gene activation in maize endosperm and embryo. Many genes involved in embryogenesis and seed development were found differentially methylated in embryo and endosperm. We found 17 endosperm-specific expressed imprinting genes were hypomethylated in endosperm and were hypermethylated in embryo. The expression of a maize DEMETER -like (DME-like) gene and MBD101 gene (MBD4 homolog) which direct bulk genome DNA demethylation were higher in endosperm than in embryo. These two genes may be associated with the distinct methylation level across maize embryo and endosperm.The methylomes of maize embryo and endosperm was obtained by MeDIP-seq method. The global mapping of maize embryo and endosperm methylation in this study broadened our knowledge of DNA methylation patterns in maize genome, and provided useful information for future studies on maize seed development and regulation of metabolic pathways in different seed tissues.

(Submitter supplied) Mouse trophoblast stem cells (TSCs) proliferate indefinitely in vitro, despite their highly heterogeneous nature. In this study, we sought to characterize TSC colony types by using methods based on cell biology and biochemistry for a better understanding of how TSCs are maintained over multiple passages. Colonies of TSCs could be classified into four major types: type 1 is compact and dome-shaped, type 4 is flattened but with a large multilayered cell cluster, and types 2 and 3 are their intermediates. more...
