Trophectoderm: The First Epithelium to Develop in the Mammalian Embryo [PDF]

, 1987
The first epithelium to appear during mammalian embryogenesis is the trophectoderm, a polarized transporting single cell layer that comprises the wall of the blastocyst.

Isogenic human trophectoderm cells demonstrate the role of NDUFA4 and associated variants in ZIKV infection

iScience, 2023
Summary: Population-based genome-wide association studies (GWAS) normally require a large sample size, which can be labor intensive and costly. Recently, we reported a human induced pluripotent stem cell (hiPSC) array-based GWAS method, identifying ...

A Role for Borg5 During Trophectoderm Differentiation

Stem Cells, 2010
Abstract Stem cell differentiation is accompanied by a gradual cellular morphogenesis and transcriptional changes. Identification of morphological regulators that control cell behavior during differentiation could shed light on how cell morphogenesis is coupled to transcriptional changes during development. By analyzing cellular behavior

Effect of Different Volume of Microdrop Culture on B6D2F1 Mice Oogenesis

Journal of Animal Reproduction and Biotechnology, 2016
This study was conducted to evaluate the effects of different volume (100 μl vs. 2 ml) of microdrop culture on B6D2F1 mice oogenesis. In the present study, B6D2F1/CrljOri F1 mice were utilized in order to maximize oogenesis.

The Interplay of Curvature, Geometry, and Topology Shapes Tissue Organisation in Epithelial Shells

Advanced Science, EarlyView.
Purely geometric 3D Voronoi models predict the organisation of epithelial shells. The interplay of curvature, geometry, and topology enriches the number of pentagons in shells with lower number of cells. Small MDCK cysts and Mouse embryos match the top polygonal configurations in a compactness‐based ranking derived from the Voronoi model. In conclusion,

Trophectoderm differentiation to invasive syncytiotrophoblast is induced by endometrial epithelial cells during human embryo implantation

, 2020
At implantation, trophoblast derived from the trophectoderm of the blastocyst-stage embryo invades the endometrium to establish pregnancy. To understand how embryos breach the endometrial epithelium, we modelled human implantation using blastocysts or ...
