Role of carbon dioxide and ion transport in the formation of sub-embryonic fluid by the blastoderm of the Japanese quail [PDF]

, 2002
1. The explanted blastoderm of the Japanese quail was used to explore the role of ions and carbon dioxide in determining the rate of sub-embryonic fluid (SEF) production between 54 and 72 h of incubation. 2.

Ontogeny of Placental FcRn Protein During Human and Animal Pregnancy to Inform Developmental Toxicity Testing

Birth Defects Research, Volume 118, Issue 5, May 2026.
ABSTRACT Introduction Species differences exist in Fc domain‐containing molecule transfer/biodistribution to the embryo‐fetus during pregnancy. Placentation was reviewed and placental neonatal Fc receptor (FcRn) quantitation in the chorioallantoic placenta (CAP) and/or inverted yolk sac placenta (InvYSP) was investigated across species throughout ...

Id1 Stabilizes Epiblast Identity by Sensing Delays in Nodal Activation and Adjusting the Timing of Differentiation

Developmental Cell, 2019
Summary Controlling responsiveness to prevailing signals is critical for robust transitions between cell states during development. For example, fibroblast growth factor (FGF) drives naive pluripotent cells into extraembryonic lineages before ...

Epiblast grafting and in vitro embryo culture

Protocol Exchange, 2015
This protocol describes a method to graft conventional primed pluripotent stem cells (PSCs) and region-selective PSCs to different locations of post-implantation mouse epiblast followed by in vitro embryo culture. Compared to conventionally used teratoma formation assay, epiblast grafting offers a more relevant in vivo test for evaluating the primed ...

The RNA Helicase DDX6 Controls Cellular Plasticity by Modulating P-Body Homeostasis [PDF]

, 2019
Post-transcriptional mechanisms have the potential to influence complex changes in gene expression, yet their role in cell fate transitions remains largely unexplored.

Differential sensitivity of midline development to mitosis during and after primitive streak extension

Developmental Dynamics, Volume 255, Issue 5, Page 486-502, May 2026.
Abstract Background Midline establishment is a fundamental process during early embryogenesis for Bilaterians. Midline morphogenesis in non‐amniotes can occur without mitosis, through Planar Cell Polarity (PCP) signaling. By contrast, amniotes utilize both cellular processes for developing the early midline landmark, the primitive streak (PS).

Hcfc1 and Ogt Mediate Zebrafish CNS Regeneration Through Hippo/Yap Signalling

Cell Proliferation, Volume 59, Issue 5, May 2026.
This work identifies Hcfc1 and Ogt as key regulators of zebrafish CNS regeneration through modulation of Hippo/Yap signalling. Loss of Hcfc1 or Ogt activity inhibition impairs regeneration, which is restored by Yap overexpression, revealing a new regulatory axis that enhances CNS regenerative capacity.

Remarks on taxonomy of some species of Elytrigia S.L. (Triticeae) in the light of embryo morphology

Acta Societatis Botanicorum Poloniae, 2014
Embryos of 21 accessions of the genus Elytrigia s.l. were studied. Characters of scutellum, coleoptile, coleorhiza and epiblast were taken into consideration. Correlation of characters proves an independence of epiblast organogenesis.

TFAP2C regulates transcription in human naive pluripotency by opening enhancers. [PDF]

, 2018
Naive and primed pluripotent human embryonic stem cells bear transcriptional similarity to pre- and post-implantation epiblast and thus constitute a developmental model for understanding the pluripotent stages in human embryo development. To identify new

Mechanobiology in Stem Cell‐Based Bioprinting

Cell Proliferation, Volume 59, Issue 5, May 2026.
Mechanobiology in stem cell‐based bioprinting is an emerging field that bridges the mechanical conditions of the bioprinting process with the regulation of stem cell behaviour for engineering living tissues. Stresses encountered during bioprinting, together with the mechanical properties of bioinks, play a critical role in regulating stem cell ...
