Isolation of Oct4-expressing extraembryonic endoderm precursor cell lines. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:The extraembryonic endoderm (ExEn) defines the yolk sac, a set of membranes that provide essential support for mammalian embryos. Recent findings suggest that the committed ExEn precursor is present already in the embryonic Inner Cell Mass ...

Embryonic Folding

open access: yesMedEdPORTAL, 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.

open access: yesPLoS 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

open access: yesFrontiers 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 ...

Function of Bmpr1a in ES cell differentiation and cell competition [PDF]

open access: yes, 2010
Bone morphogenetic protein (BMP) 4 signalling via BMPR1A is required for the maintenance of the epiblast in the early embryo, and for self-renewal of pluripotent mouse embryonic stem (ES) cells by inhibiting neural differentiation.

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

open access: yesBiology 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.

Valores séricos de imunoglobulinas e dos componentes do complemento em gestantes com ruptura prematura de membranas Immunoglobulin serum values and complement components in pregnant women with premature rupture of the membranes

open access: yesRevista Brasileira de Ginecologia e Obstetrícia, 2007
OBJETIVO: a ruptura prematura de membranas (RPM) tem sido motivo para muitas indagações, dentre as quais os mecanismos imunes envolvidos. Diante da escassez de estudos relacionados ao tema, este trabalho teve como objetivo avaliar os valores séricos de ...
