Nature, 1963 THE homologies of the various organs of the graminaceous embryo and caryopsis have been the subject of much debate in the past. Jacques-Felix1, who recently summarized again the various theories, has suggested that the epiblast is the sole leaf of the primary axis or ‘protocorm’; other theories give the epiblast the status of an auricle, or a cotyledon.

eLife, 2015 Early mouse development is accompanied by dynamic changes in chromatin modifications, including G9a-mediated histone H3 lysine 9 dimethylation (H3K9me2), which is essential for embryonic development.

Transcription factor heterogeneity and epiblast pluripotency [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2011 Stem cells are defined by the simultaneous possession of the seemingly incongruent properties of self-renewal and multi-lineage differentiation potential. To maintain a stem cell population, these opposing forces must be balanced. Transcription factors that function to direct pluripotent cell identity are not all equally distributed throughout the ...

Nanog regulates Pou3f1 expression at the exit from pluripotency during gastrulation
Biology Open, 2019 Pluripotency is regulated by a network of transcription factors that maintain early embryonic cells in an undifferentiated state while allowing them to proliferate.

Sox2 Level Is a Determinant of Cellular Reprogramming Potential. [PDF]
PLoS ONE, 2013 Epiblast stem cells (EpiSCs) and embryonic stem cells (ESCs) differ in their in vivo differentiation potential. While ESCs form teratomas and efficiently contribute to the development of chimeras, EpiSCs form teratomas but very rarely chimeras.

Epigenetic regulation of gene expression in porcine epiblast, hypoblast, trophectoderm and epiblast-derived neural progenitor cells [PDF]
Epigenetics, 2011 After fertilization, lineage specification is governed by a complicated molecular network in which permissiveness and repression of expression of pluripotency- and differentiation-associated genes are regulated by epigenetic modifications. DNA methylation operates as a very stable repressive mark in this process.

Stem Cell Research, 2021 The tyrosine kinase Src is highly expressed in embryonic stem cells (ESCs) and ESC-differentiated cells, however, its functional role remains obscured. Here, we constitutively expressed Src in mouse ESCs and found these cells retained comparable levels ...

Stable Methylation at Promoters Distinguishes Epiblast Stem Cells from Embryonic Stem Cells and the In Vivo Epiblasts [PDF]
Stem Cells and Development, 2014 Embryonic Stem Cells (ESCs) and Epiblast Stem Cells (EpiSCs) are the in vitro representatives of naïve and primed pluripotency, respectively. It is currently unclear how their epigenomes underpin the phenotypic and molecular characteristics of these distinct pluripotent states. Here, we performed a genome-wide comparison of DNA methylation between ESCs

Human ES Cell Culture Conditions Fail to Preserve the Mouse Epiblast State
Stem Cells International, 2021 Mouse embryonic stem cells (mESCs) and mouse epiblast stem cells (mEpiSCs) are the pluripotent stem cells (PSCs), derived from the inner cell mass (ICM) of preimplantation embryos at embryonic day 3.5 (E3.5) and postimplantation embryos at E5.5-E7.5 ...

Short-Circuiting Epiblast Development [PDF]
Cell Stem Cell, 2007 Although human and mouse embryonic stem cells share many characteristics, their behaviors are not identical. Two recent papers describe the derivation of stem cell lines from mouse epiblast that may provide an explanation for the unique character of human embryonic stem cells.
