(Submitter supplied) We report for the first time, the derivation and characterization of extra-embryonic endoderm (XEN) cells from primitive endoderm (PrE) of porcine (p) embryos. The pXEN cells can be reliably and reproducibly generated from parthenogenic, in vitro or in vivo derived embryos, and express canonical PrE or XEN cell genes (GATA4, GATA6, SOX17, SALL4, FOXA2, and HNF4A). Transcriptome analysis of pXEN cells revealed close resemblance to yolk sac than any other embryonic or extraembryonic tissue. more...

(Submitter supplied) We detected the gene expression differences between porcine extra-embryonic endoderm cells and naïve like and primed porcine ESCs. Gene expression of porcine extra-embryonic endoderm cells was distinct with porcine naïve like and primed embryonic stem cells. Pearson correlation analysis confirmed that porcine naïve like and primed ESCs have stronger correlation than the correlation between either pXEN cells and porcine naïve like ESCs or primed ESCs. more...

(Submitter supplied) In this study we showed that rat XEN cells grown in the presence of a GSK3 inhibitor exhibited enhanced formation of cell contacts and decreased motility. In contrast, treatment with forskolin induced the PE formation and epithelial-mesenchymal transition (EMT) in rat XEN cells. Using microarray and real-time PCR assays, we found that VE versus PE formation of rat XEN cells was correlated with change in expression levels of VE or PE marker genes. more...

(Submitter supplied) XEN cells are derived from the primitive endoderm of mouse blastocysts. In culture and in chimeras they exhibit properties of parietal endoderm. However, BMP signaling promotes XEN cells to form an epithelium and differentiate into visceral endoderm (VE). Of the several different subtypes of VE described, BMP induces a subtype that is most similar to the VE adjacent to the trophoblast-derived extraembryonic ectoderm. more...

(Submitter supplied) Stem cells self-renew or differentiate under the governance of a stem cell-specific transcriptional program with each transcription factor orchestrating the activities of a particular set of genes. Here we demonstrate that a single transcription factor is able to regulate distinct core circuitries in two different blastocyst-derived stem cell lines, embryonic stem (ES) and extra-embryonic endoderm (XEN) cells. more...

(Submitter supplied) The visceral endoderm (VE) is an epithelial tissue in the early postimplantation mouse embryo that encapsulates the pluripotent epiblast distally and the extraembryonic ectoderm proximally. In addition to facilitating nutrient exchange before the establishment of a circulation, the VE is critical for patterning the epiblast. Since VE is derived from the primitive endoderm (PrE) of the blastocyst, and PrE-derived eXtraembryonic ENdoderm (XEN) cells can be propagated in vitro, XEN cells should provide an important tool for identifying factors that direct VE differentiation. more...

(Submitter supplied) The signaling pathway for Nodal, a ligand of the transforming growth factor-beta (TGF-beta) superfamily, plays a central role in regulating the maintenance and/or differentiation of stem cell types that can be derived from the peri-implantation mouse embryo. Extraembryonic endoderm stem (XEN) cells are derived from the primitive endoderm of the blastocyst, which normally gives rise to the parietal and the visceral endoderm in vivo, but XEN cells do not contribute efficiently to the visceral endoderm in chimeric embryos. more...

(Submitter supplied) Comparison of mouse ES cells and three different XEN cell cultures. Three XEN cell cultures: Two different strains (IM8A1 is PO, and XEN1-3 is ICR). And two different culture conditions (IM8A1-I versus IM8A1-II). Three biological replicates of XEN cell RNA were submitted to the Centre for Applied Genomics at the Hospital for Sick Children (Toronto, Canada) for preparation of cRNA and hybridization to the mouse U74Av2 Affymetrix gene array. more...

Analysis of blastocyst-derived extra-embryonic endoderm (XEN) cell lines and an embryonic stem (ES) cell line. Results identify independent XEN cell lines that express markers of extra-embryonic endoderm, but not those of the epiblast, and thus represent a new model of an early mammalian lineage.

The two surface markers can be co-detected on a third subpopulation, expressing epiblast and PrE determinants.

(Submitter supplied) To understand the role of Sox7 in primitive endoderm differentiation, we compare the gene expression pattern of Sox7 (+/-) and Sox7 (-/-) ES cells with or without dexamethasome (Dex) treatment. Because these ES cells harbour Gata6-GR transgene, Dex treatment forces ES cells differentate into XEN-like cells. As Sox7 (-/-) ES cells can differentiate into XEN-like cell by morphology, we assessed genome wide gene expression pattern.

(Submitter supplied) During development, progenitors of embryonic stem (ES) and extraembryonic endoderm stem (XEN) cells are concomitantly specified within the inner cell mass (ICM) of the mouse blastocyst. Similarly, XEN cells are induced (iXEN cells) alongside induced pluripotent stem (iPS) cells following overexpression ofOct4,Sox2,Klf4andMyc(OSKM) during somatic cell reprogramming. It is unclear how or why this cocktail produces both stem cell types, but OCT4 has been associated with non-pluripotent outcomes. more...

(Submitter supplied) Small-molecule based lineage reprogramming has newly emerged as a promising approach for generating functional cell types. We recently found that the chemical induction of iPSCs from fibroblasts pass through an extra-embryonic endoderm (XEN)-like state. In this study, we demonstrated that these chemically-induced XEN-like cells were not restricted to be reprogrammed to iPSCs, but feasible to be induced into functional neurons, bypassing the pluripotent stage. more...

(Submitter supplied) Klf5 has essential functions during early embryogenesis and in the derivation of ES cells from inner-cell mass of blastocyst. Among Kruppel-like factor (Klf) family members, only Klf5 shows peri-implantation lethal phenotype, but the precise mechanisms still remain unknown. To understand and identify molecular mechanisms, we performed microarray analysis by using E3.0 WT and Klf5 KO embryos when first phenotype of Klf5 deficiency appears.

(Submitter supplied) Embryonic stem cells (ESCs) favor glycolysis over oxidative phosphorylation for energy production, and glycolytic metabolism is critical for pluripotency establishment, maintenance and exit. However, how glycolysis regulates the self-renewal and differentiation of ESCs remains elusive. Here, we demonstrated that protein lactylation, regulated by intracellular lactate, contributes to the self-renewal of ESCs. more...
