#176 : The Relationship Between Blastocyst Morphology and PGD Result

open access: yesFertility & Reproduction, 2023
Background and Aims: Blastocyst morphology has been clinically assessed during the selection of blastocyst for transfer and cryopreservation, and the morphological grading scheme has gained wide acceptance. Blastocyst grading according to Gardner et al. (

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

open access: yesJournal 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

open access: yesScientific 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]

open access: yesPLoS 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

Laser-assisted hatching in lower grade cleavage stage embryos improves blastocyst formation: results from a retrospective study

open access: yesJournal of Ovarian Research, 2021
Background Laser-assisted hatching (LAH) has been widely applied to facilitate blastocyst hatching in IVF-ET treatment, however, the effect of LAH on subsequent development and clinical outcomes of the lower grade cleavage stage embryos (LGCE) remains ...

Pluripotent Stem Cells as a Model for Human Embryogenesis

open access: yesCells, 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 ...

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

open access: yesFrontiers 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 ...

Pre-implantation mouse embryos cultured In vitro under different oxygen concentrations show altered ultrastructures [PDF]

open access: yes, 2020
Assisted Reproductive Technologies routinely utilize different culture media and oxygen (O2) concentrations to culture human embryos. Overall, embryos cultured under physiological O2 tension (5%) have improved development compared to embryos cultured ...
