The effect of cadmium on the bovine in vitro oocyte maturation and early embryo development [PDF]

open access: yes, 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.

Blastocyst-induced changes in the bovine endometrial transcriptome.

open access: yesReproduction, 2018
The objectives of this study were (i) to determine whether blastocyst-induced responses in endometrial explants were detectable after 6- or 24-h co-culture in vitro; (ii) to test if direct contact is required between embryos and the endometrial surface ...

ZNHIT3 Regulates Translation to Ensure Cell Lineage Differentiation in Mouse Preimplantation Development

open access: yesAdvanced Science, EarlyView.
Box C/D snoRNP complex regulates protein translation. This study identifies ZNHIT3 as a key component of the complex and ensures normal protein expression, including transcription factors orchestrating cell fate commitment, during early mouse embryogenesis.

Epicatechin Gallate Decreases the Viability and Subsequent Embryonic Development of Mouse Blastocysts

open access: yesTaiwanese Journal of Obstetrics & Gynecology, 2010
Objective: Catechins, a family of polyphenols found in tea, evoke various responses including cell death. We examined the cytotoxic effects of epicatechin gallate (ECG), a polyphenol extract from green tea, on the blastocyst stage of mouse embryos ...

Should extended blastocyst culture include Day 7?

open access: yesHuman Reproduction, 2018
Extended culture to the blastocyst stage is widely practised, improving embryo selection and promoting single embryo transfer. Selection of useable blastocysts typically occurs on Days 5 and 6 of embryo culture.

Sperm‐Derived CircRNA‐1572 Regulates Embryogenesis and Zygotic Genome Activation by Targeting CCNB2 via Bta‐miR‐2478‐L‐2

open access: yesAdvanced Science, EarlyView.
Sperm‐derived circRNA‐1572 competitively binds to bta‐miR‐2478‐L‐2 through a “sponge” mechanism to regulate cyclin B2 (CCNB2) expression, thereby modulating the distribution of fibrous actin (F‐actin) in early pig embryos, ensuring proper chromosome segregation during mitosis, and facilitating normal embryo cleavage and zygotic genome activation.

Comparison of Quinn's Advantage fertilization medium and tissue culture medium 199 for in vitro maturation of oocytes

open access: yesTaiwanese Journal of Obstetrics & Gynecology, 2014
Objective: The purpose of the study was to compare the Quinn's Advantage fertilization medium (Q1) and the tissue culture medium 199 (TCM199) for in vitro maturation (IVM) of oocytes and ammonium production during IVM. Materials and methods: The immature

Human Blastocyst Classification after In Vitro Fertilization Using Deep Learning [PDF]

open access: yesarXiv, 2020
Embryo quality assessment after in vitro fertilization (IVF) is primarily done visually by embryologists. Variability among assessors, however, remains one of the main causes of the low success rate of IVF. This study aims to develop an automated embryo assessment based on a deep learning model.

A Critical Examination of the Question of Personhood in Stem Cell Research [PDF]

open access: yes, 2016
Stem cell research programme has been celebrated world over as the most promising medical research in the 21st century. However, the method of stem cell research involves the use and unavoidable destruction of human embryo.

Modeling human trophoblast, the placental epithelium at the maternal fetal interface. [PDF]

open access: yes, 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
