Blastocyst score, a blastocyst quality ranking tool, is a predictor of blastocyst ploidy and implantation potential [PDF]

F&S Reports, 2020
To convert blastocyst (BL) morphological grade and BL day into a numeric blastocyst score (BS).Retrospective cohort study.Academic center.A total of 5,653 BL of known implantation (fetal heart, FH) and 11,348 biopsied BL.Based on their FH rates and/or significance, a score (1-4) was assigned to each BL grade component.

Comparison of clinical outcomes of frozen-thawed D5 and D6 blastocysts undergoing preimplantation genetic testing

Journal of Translational Medicine, 2022
Background This study aimed to analyze the clinical outcomes of blastocyst which undergo the preimplantation genetic testing (PGT) transplantation from frozen-thawed D5 and D6. In addition, the effect of blastocyst grade on clinical and neonatal outcomes

An artificial intelligence algorithm for automated blastocyst morphometric parameters demonstrates a positive association with implantation potential

Scientific Reports, 2023
Blastocyst selection is primarily based on morphological scoring systems and morphokinetic data. These methods involve subjective grading and time-consuming techniques. Artificial intelligence allows for objective and quick blastocyst selection.

p38 MAPK regulates cavitation and tight junction function in the mouse blastocyst. [PDF]

PLoS ONE, 2013
Blastocyst formation is essential for implantation and maintenance of pregnancy and is dependent on the expression and coordinated function of a series of proteins involved in establishing and maintaining the trans-trophectoderm ion gradient that enables

Pluripotent Stem Cells as a Model for Human Embryogenesis

Cells, 2023
Pluripotent stem cells (PSCs; embryonic stem cells and induced pluripotent stem cells) can recapitulate critical aspects of the early stages of embryonic development; therefore, they became a powerful tool for the in vitro study of molecular mechanisms ...

Frozen blastocysts: Assessing the importance of day 5/day 6 blastocysts or blastocyst quality

Experimental and Therapeutic Medicine, 2022
The aim of the present study was to analyze the high-quality blastocyst (HB) rate in all embryo frozen cycles and investigate the pregnancy outcomes for day 5/day 6 (D5/D6) blastocysts with respect to the blastocyst quality in programmed single vitrified-warmed blastocyst transfer (SVBT).

Biophysical models of early mammalian embryogenesis

Stem Cell Reports, 2023
Summary: Embryo development is a critical and fascinating stage in the life cycle of many organisms. Despite decades of research, the earliest stages of mammalian embryogenesis are still poorly understood, caused by a scarcity of high-resolution spatial ...

Placental deficiency of the (pro)renin receptor ((P)RR) reduces placental development and functional capacity

Frontiers in Cell and Developmental Biology, 2023
The (pro)renin receptor ((P)RR; also known as ATP6AP2) is a multifunctional receptor. The (P)RR activates the tissue renin-angiotensin system (RAS) and is also involved in regulating integral intracellular pathways such as V-ATPase and Wnt/β-catenin ...
