In vitro production of bovine embryos derived from individual donors in the Corral® dish [PDF]

, 2017
Background: Since the identity of the embryo is of outmost importance during commercial in vitro embryo production, bovine oocytes and embryos have to be cultured strictly per donor.

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

Correlation of the position and status of the polar body from the fertilized oocyte to the euploid status of blastocysts

Frontiers in Genetics, 2022
Polar bodies are tiny cells that are extruded during oocyte meiosis and are generally considered not essential for embryonic development. Therefore, polar bodies have been widely used as important materials for the preimplantation genetic diagnosis of ...

Progesterone governs endometrial proliferation-differentiation switching and blastocyst implantation.

Endocrine journal, 2019
Blastocyst implantation contains the following three processes: apposition, attachment, and invasion of the blastocyst. Ovarian hormone progesterone (P4) regulates these processes exquisitely.

Telomere lengths in human oocytes, cleavage stage embryos and blastocysts [PDF]

, 2010
Telomeres are repeated sequences that protect the ends of chromosomes and harbour DNA-repair proteins. Telomeres shorten during each cell division in the absence of telomerase.

Survival of bovine blastocysts produced in vitro and vitrified in vitri-tip and vitri-top devices. [PDF]

SPERMOVA, 2019
Vitrification is a new technique that has many potential advantages in mammalian oocytes and embryos. In the present work, the objective was to compare of post thawing survival rate by of blastocysts vitrified in vitro in two devices.

Regulated mitochondrial DNA replication during oocyte maturation is essential for successful porcine embryonic development. [PDF]

, 2006
Cellular ATP is mainly generated through mitochondrial oxidative phosphorylation, which is dependent on mitochondrial DNA (mtDNA). We have previously demonstrated the importance of oocyte mtDNA for porcine and human fertilization.

Nested Selves: Self‐Organization and Shared Markov Blankets in Prenatal Development in Humans

Topics in Cognitive Science, EarlyView., 2023
Abstract The immune system is a central component of organismic function in humans. This paper addresses self‐organization of biological systems in relation to—and nested within—other biological systems in pregnancy. Pregnancy constitutes a fundamental state for human embodiment and a key step in the evolution and conservation of our species. While not

The Open Cryotop System Is Effective for the Simultaneous Vitrification of a Large Number of Porcine Embryos at Different Developmental Stages

Frontiers in Veterinary Science, 2022
The Superfine Open Pulled Straw (SOPS) system is the most commonly used method for vitrification of pig embryos. However, this system only allows the vitrification of four to seven embryos per straw.

Overall Blastocyst Quality, Trophectoderm Grade, and Inner Cell Mass Grade Predict Pregnancy Outcome in Euploid Blastocyst Transfer Cycles

Chinese Medical Journal, 2018
Background: Despite recent advances that have improved the pregnancy success rates that can be achieved via in vitro fertilization (IVF) therapy, it is not yet clear which blastocyst morphological parameters best predict the outcomes of single blastocyst
