The Long Terminal Repeats of ERV6 Are Activated in Pre-Implantation Embryos of Cynomolgus Monkey

open access: yesCells, 2021
Precise gene regulation is critical during embryo development. Long terminal repeat elements (LTRs) of endogenous retroviruses (ERVs) are dynamically expressed in blastocysts of mammalian embryos.

Capturing Pluripotency and Beyond

open access: yesCells, 2021
During the development of a multicellular organism, the specification of different cell lineages originates in a small group of pluripotent cells, the epiblasts, formed in the preimplantation embryo.

Epiblast cells gather onto the anterior mesendoderm and initiate brain development without the direct involvement of the node in avian embryos: Insights from broad-field live imaging

open access: yesFrontiers in Cell and Developmental Biology, 2022
Live imaging of migrating and interacting cells in developing embryos has opened a new means for deciphering fundamental principles in morphogenesis and patterning, which was not possible with classic approaches of experimental embryology.

Blastomeres of 8-cell mouse embryos differ in their ability to generate embryonic stem cells and produce lines with different transcriptional signatures

open access: yesFrontiers in Cell and Developmental Biology, 2023
Embryonic stem cell (ESC) derivation from single blastomeres of 8-cell mouse embryos results in lower derivation rates than that from whole blastocysts, raising a biological question about the developmental potential of sister blastomeres.

Integrin β1 coordinates survival and morphogenesis of the embryonic lineage upon implantation and pluripotency transition

open access: yesCell Reports, 2021
Summary: At implantation, the embryo establishes contacts with the maternal endometrium. This stage is associated with a high incidence of preclinical pregnancy losses. While the maternal factors underlying uterine receptivity have been investigated, the

Epithelial-Mesenchymal Transition Drives Three-Dimensional Morphogenesis in Mammalian Early Development

open access: yesFrontiers in Cell and Developmental Biology, 2021
From fertilization to onset of gastrulation, a mammalian embryo goes through several rounds of cellular morphogenesis resembling phenomena of epithelial-mesenchymal transition (EMT) and mesenchymal-epithelial transition (MET), collectively referred to as

An in vitro stem cell model of human epiblast and yolk sac interaction

open access: yeseLife, 2021
Human embryogenesis entails complex signalling interactions between embryonic and extra-embryonic cells. However, how extra-embryonic cells direct morphogenesis within the human embryo remains largely unknown due to a lack of relevant stem cell models ...

Rat epiblast-derived stem cells recapitulate the attributes of pre-gastrulation epiblast

open access: yesCell Reports Methods, 2023
Iwatsuki and colleagues have generated self-renewing pluripotent stem cells from the pre-gastrulation epiblast of the rat embryo and from other cellular sources: rat embryonic stem cells (rESCs) and epiblast-like cells derived from the rESCs. These rat epiblast-derived stem cells (rEpiSCs) display germ-line competence that is characteristic of mouse ...

BET proteins are essential for the specification and maintenance of the epiblast lineage in mouse preimplantation embryos

open access: yesBMC Biology, 2022
Background During mammalian preimplantation development, as the fertilized egg develops and differentiates, three cell lineages become specified: trophectoderm (TE), epiblast, and primitive endoderm (PrE).

Micropattern differentiation of mouse pluripotent stem cells recapitulates embryo regionalized cell fate patterning

open access: yeseLife, 2018
During gastrulation epiblast cells exit pluripotency as they specify and spatially arrange the three germ layers of the embryo. Similarly, human pluripotent stem cells (PSCs) undergo spatially organized fate specification on micropatterned surfaces ...
