Role of CEBPa in trophectoderm competence installment [PDF]

Science Advances
During mouse embryogenesis, totipotency is gradually lost, and, at the 16-cell stage, blastomeres begin to bifurcate into trophectoderm (future placenta) and inner cell mass (future fetus).

Mosaicism in the mouse trophectoderm

Tissue and Cell, 1990
The issue of mosaicism in the mouse trophectoderm is examined by reviewing two sets of evidence: one arguing for a mosaic, the other for a non-mosaic character.

Trophectoderm, Inner Cell Mass, and Expansion Status for Live Birth Prediction After Frozen Blastocyst Transfer: The Winner Is Trophectoderm

Life
Despite advancements in technologies such as time-lapse microscopy and artificial intelligence, the gold standard for embryo selection still relies on standard morphological assessment. Several studies have investigated the correlation between blastocyst

Trophectoderm growth and bilateral symmetry of the blastocyst in the mouse. [PDF]

Human Reproduction, 2002
BACKGROUND: The present study was undertaken to ascertain whether the polarized flow of cells from polar to mural trophectoderm is related to the axis of bilateral symmetry of the blastocyst in the mouse, and whether trophectoderm cells can initiate new ...

NuRD-dependent DNA methylation prevents ES cells from accessing a trophectoderm fate [PDF]

Biology Open, 2012
Summary Embryonic Stem (ES) cells are able to give rise to the three germ layers of the embryo but are prevented from contributing to the trophoblast. The molecular nature of this barrier between embryonic and trophectodermal cell fates is not clear, but

Computational modelling unveils how epiblast remodelling and positioning rely on trophectoderm morphogenesis during mouse implantation. [PDF]

PLoS ONE, 2021
Understanding the processes by which the mammalian embryo implants in the maternal uterus is a long-standing challenge in embryology. New insights into this morphogenetic event could be of great importance in helping, for example, to reduce human ...

CEBPa is an orchestrator of trophectoderm specification [PDF]

La bifurcación entre trofoectodermo y la masa celular interna es la decisión de desarrollo más temprana, pero cómo se inicia y en qué etapa embrionaria ocurre no se entiende completamente.

Livestock Blastoids: In Vitro Blastocyst Models for Embryogenesis and Reproductive Technologies. [PDF]

Reprod Domest Anim
ABSTRACT Understanding early embryogenesis in livestock remains a persistent bottleneck in both reproductive biology and animal breeding. Work in domestic species has long been limited by restricted access to embryos, ethical considerations, and the complexity of peri‐implantation development, making mechanistic studies difficult.

Pregnancy Outcomes Following Artificial Insemination and Embryo Transfer in Dairy Cows-Expectations vs. Reality. [PDF]

Reprod Domest Anim
ABSTRACT Bovine embryo transfer (ET) has been a consistently growing market worldwide with in vitro produced (IVP) embryos now far outnumbering those produced by traditional superovulation. Because transfer of a viable blastocyst‐stage embryo to the uterus bypasses many of the potential biological causes of early pregnancy failure associated with ...

Trophectoderm Lineage Determination in Cattle [PDF]

Developmental Cell, 2011
The trophectoderm (TE) and inner cell mass (ICM) are committed and marked by reciprocal expression of Cdx2 and Oct4 in mouse late blastocysts. We find that the TE is not committed at equivalent stages in cattle, and that bovine Cdx2 is required later, for TE maintenance, but does not repress Oct4 expression.
