Live imaging and functional characterization of the avian hypoblast redefine the mechanisms of primitive streak induction [PDF]
Nature CommunicationsIn birds and mammals, the formation of the primitive streak, the hallmark of the primary axis and site of gastrulation, is thought to occur when the anterior displacement of the hypoblast (visceral endoderm in mice) lifts its inhibition on NODAL ...

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

YAP1 and QSER1 are key modulators of embryonic signaling pathways in the mammalian epiblast [PDF]
EMBO ReportsYAP1 signaling is essential for development but its specific roles in early embryogenesis remain poorly understood. To shed light on this, we analyze YAP1’s role in regulating the pluripotency of the mammalian epiblast, using scRNAseq approaches ...

The potent neuroepithelium-promoting activity of Otx2 during gastrulation, as demonstrated by its exogenous epiblast-wide expression in chicken embryos [PDF]
Frontiers in Cell and Developmental BiologyAlthough 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]
Animal 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
Cells, 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
Cells, 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.
