Trophoblast biology: Forum introduction

Reproductive Biology and Endocrinology, 2004
In mammals, a carefully orchestrated dialogue between the mother and conceptus (embryo/fetus and associate extraembryonic membranes) is initiated during the peri-implantation period of pregnancy as the trophoblast develops, functions to signal pregnancy ...

The effect of methenamine on vascular development: Experimental investigation using in vivo and insilico methods

International Journal of Reproductive BioMedicine, 2020
Background: Methenamine is a worldwide antibacterial agent for urinary system infections in human and animals. The effect of methenamine consumption during early phase of pregnancy is not fully clarified in previous studies.

Concomitant Morphological Modifications of the Avian Eggshell, Eggshell Membranes and the Chorioallantoic Membrane During Embryonic Development

Frontiers in Physiology, 2022
The chicken eggshell (ES) consists of 95% calcium carbonate and 3.5% organic matter, and represents the first physical barrier to protect the developing embryo, while preventing water loss.

Laminin γ1 C-terminal Glu to Gln mutation induces early postimplantation lethality

Life Science Alliance, 2018
Mouse embryos with an ablated ability of integrins to bind laminins are still able to form basement membranes, but die just after implantation because of deficient extraembryonic development.

Periostin as a Biomarker of the Amniotic Membrane

Stem Cells International, 2012
Tracing the precise developmental origin of amnion and amnion-derived stem cells is still challenging and depends chiefly on analyzing powerful genetic model amniotes like mouse. Profound understanding of the fundamental differences in amnion development

Dichloroaniline retention by nanofiltration membranes [PDF]

, 2005
This study evaluates the performance of two nanofiltration membranes in removing a herbicide: dichloroaniline. The membranes, one polyamide and one cellulose acetate, have a cut-off in the range 150–300 g/mol (manufacturers’ data).

Epithelial-mesenchymal transition and bi- and multi-nucleated trophoblast cell formation in ovine conceptuses during the peri-implantation period

The Journal of Reproduction and Development, 2022
Epithelial-mesenchymal transition (EMT), which is common in cancer metastasis, is also observed during developmental processes such as embryo implantation into the maternal endometrium in humans and rodents.

Lineage Differentiation Markers as a Proxy for Embryo Viability in Farm Ungulates

Frontiers in Veterinary Science, 2021
Embryonic losses constitute a major burden for reproductive efficiency of farm animals. Pregnancy losses in ungulate species, which include cattle, pigs, sheep and goats, majorly occur during the second week of gestation, when the embryo experiences a ...

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

PLoS 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 ...
