Embryonic Folding

MedEdPORTAL, 2007
Introduction Embryology is a challenging subject to learn because it involves three-dimensional structures within the embryo that are constantly changing as development proceeds. This animated module depicts embryonic folding, in which the flat embryonic

Vertical transmission of African-lineage Zika virus through the fetal membranes in a rhesus macaque (Macaca mulatta) model.

PLoS Pathogens, 2023
Zika virus (ZIKV) can be transmitted vertically from mother to fetus during pregnancy, resulting in a range of outcomes including severe birth defects and fetal/infant death.

Male Embryos Produced in vitro Deviate From Their in vivo Counterparts in Placental Gene Expression on Day 32 of Pregnancy

Frontiers in Animal Science, 2022
This study compared the gene expression of extraembryonic membranes (EEM) from in vitro produced (IVP) and in vivo (AI) derived pregnancies. A piece of conceptus (day 18) or chorioallantois (day 32) was used for DNA and RNA isolation and sex ...

Yolk syncytial layer formation is a failure of cytokinesis mediated by Rock1 function in the early zebrafish embryo

Biology Open, 2012
Summary The yolk syncytial layer (YSL) performs multiple critical roles during zebrafish development. However, little is known about the cellular and molecular mechanisms that underlie the formation of this important extraembryonic structure.
