Suppression of ERK signalling promotes pluripotent epiblast in the human blastocyst [PDF]

open access: yesNature Communications
Studies in the mouse demonstrate the importance of fibroblast growth factor (FGF) and extra-cellular receptor tyrosine kinase (ERK) in specification of embryo-fated epiblast and yolk-sac-fated hypoblast cells from uncommitted inner cell mass (ICM) cells ...

Tracing and Capturing the Epiblast Pluripotency of Sheep Preimplantation Embryos [PDF]

open access: yesAdvanced Science
Capturing different pluripotent state stem cells from epiblast in vitro helps understand embryonic development and provides invaluable cell sources for basic research and regenerative medicine.

Src-Yap1 signaling axis controls the trophectoderm and epiblast lineage differentiation in mouse embryonic stem cells

open access: goldStem 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 ...

Use of Insulin to Increase Epiblast Cell Number: Towards a New Approach for Improving ESC Isolation from Human Embryos [PDF]

open access: hybrid, 2013
Human embryos donated for embryonic stem cell (ESC) derivation have often been cryopreserved for 5–10 years. As a consequence, many of these embryos have been cultured in media now known to affect embryo viability and the number of ESC progenitor ...

Large‐Scale Bioprinting of Human Epiblast‐Like Models Featuring Disc‐Shaped Morphogenesis and Gastrulation Events [PDF]

open access: yesAdvanced Science
Understanding the initial weeks of human development remains challenging due to ethical concerns and the restricted availability of human embryos.

Inverse agonism of retinoic acid receptors directs epiblast cells into the paraxial mesoderm lineage

open access: goldStem Cell Research, 2018
We have investigated the differentiation of paraxial mesoderm from mouse embryonic stem cells utilizing a Tbx6-EYFP/Brachyury (T)-Cherry dual reporter system.

The potent neuroepithelium-promoting activity of Otx2 during gastrulation, as demonstrated by its exogenous epiblast-wide expression in chicken embryos [PDF]

open access: yesFrontiers in Cell and Developmental Biology
Although Otx2 has been a topic of research for over 3 decades, the role of Otx2 expressed in the brain-forming anterior epiblast during gastrulation has not been clarified.

The number of primitive endoderm cells in the inner cell mass is regulated by platelet-derived growth factor signaling in porcine preimplantation embryos [PDF]

open access: yesAnimal Bioscience, 2023
Objective Discovering the mechanism of cell specification is important to manipulate cellular lineages. To obtain lineage-specific cell lines, the target lineage needs to be promoted, and counterpart lineages should be suppressed.

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.
