Prostaglandins in Swine Blastocysts [PDF]
Biology of Reproduction, 1983 The activity of phospholipase A2 (PLA2) and the content of prostaglandins (PGF and PGE-A) in swine blastocysts were determined on Days 7 through 14 of gestation by using radioenzymatic and radioimmunoassay techniques. Both PLA2 activity and PG content increased in the blastocyst with age.

Reproductive Biology and Endocrinology, 2019 Background Blastomere movement (BMov) occurs after the first cell division in human embryos. This movement has been suggested as a prognostic parameter for pregnancy outcome prediction following cleavage-stage embryo transfer. However, the effect of BMov

Leukemia Inhibitory Factor Stimulates Primitive Endoderm Expansion in the Bovine Inner Cell Mass
Frontiers in Animal Science, 2021 Previous work determined that bovine interleukin-6 (IL6) increases inner cell mass (ICM), primitive endoderm (PE), and total cell number in in vitro produced (IVP) bovine blastocysts.

Repeats as global DNA methylation marker in bovine preimplantation embryos [PDF]
, 2017 DNA methylation undergoes dynamic changes and is a crucial part of the epigenetic regulation during mammalian early development. To determine the DNA methylation levels in bovine embryos, we applied a bisulfite sequencing based method aimed at repetitive

Morphogenesis of the mammalian blastocyst
Molecular and Cellular Endocrinology, 2008 The first 4 days of mouse pre-implantation development are characterized by a period of segmentation, including morphogenetic events that are required for the divergence of embryonic and extra-embryonic lineages. These extra-embryonic tissues are essential for the implantation into the maternal uterus and for the development of the foetus.

Cleavage stage versus blastocyst stage embryo transfer in assisted reproductive technology.
Cochrane Database of Systematic Reviews, 2016 BACKGROUND Advances in cell culture media have led to a shift in in vitro fertilisation (IVF) practice from cleavage stage embryo transfer to blastocyst stage transfer.

The effect of cadmium on the bovine in vitro oocyte maturation and early embryo development [PDF]
, 2019 Common pollutants such as heavy metals and cadmium is among those with high environmental concerns. In vivo studies had shown that cadmium (Cd) causes oocyte degeneration and embryo mortality, and lowers pregnancy rates in mammals.

Modeling human trophoblast, the placental epithelium at the maternal fetal interface. [PDF]
, 2020 Appropriate human trophoblast lineage specification and differentiation is crucial for the establishment of normal placentation and maintenance of pregnancy. However, due to the lack of proper modeling systems, the molecular mechanisms of these processes
