Evaluating the Development and the Expression of Bax, Bcl-2, and ErbB4 Genes following Vitrification of Eight Cell and Blastocyst Embryos [PDF]

Journal of Advanced Biomedical Sciences, 2014
Background & Objective: Vitrification is an effective mean for preserving embryos. During this process, expression of implanting and apoptotic genes changes and can affect the quality of embryos.

Expression of mutant TIE2 p.L914F during mouse development causes embryonic lethality and defects in vascular remodeling

Developmental Dynamics, EarlyView.
Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.

EfficientNet-B0 outperforms other CNNs in image-based five-class embryo grading: a comparative analysis

Journal of Animal Reproduction and Biotechnology
Background: Evaluating embryo quality is crucial for the success of in vitro fertilization procedures. Traditional methods, such as the Gardner grading system, rely on subjective human assessment of morphological features, leading to potential ...

PTPN11 (SHP2) Is Indispensable for Growth Factors and Cytokine Signal Transduction During Bovine Oocyte Maturation and Blastocyst Development

Cells, 2019
This study was aimed to investigate the role of SHP2 (Src-homology-2-containing phosphotyrosine phosphatase) in intricate signaling networks invoked by bovine oocyte to achieve maturation and blastocyst development.

The Transcription Factor OVOL2 Represses ID2 and Drives Differentiation of Trophoblast Stem Cells and Placental Development in Mice

Cells, 2020
Trophoblasts are the first cell type to be specified during embryogenesis, and they are essential for placental morphogenesis and function. Trophoblast stem (TS) cells are the progenitor cells for all trophoblast lineages; control of TS cell ...

Time from trophectoderm biopsy to vitrification affects the developmental competence of biopsied blastocysts

Reproductive Medicine and Biology, 2022
Purpose The present study aimed to examine the correlations of the time interval from trophectoderm (TE) biopsy to vitrification with the blastocyst survival rate and blastocyst outgrowth ability.

Bridging maternal effects and epitranscriptomics: A novel perspective in developmental biology

Developmental Dynamics, EarlyView.
Abstract Maternal effects, encompassing both genetic (maternally expressed gene products) and non‐genetic (maternal state) influences, are powerful determinants of offspring phenotype, yet their RNA‐level mechanisms remain incompletely resolved. In parallel, epitranscriptomics, an emerging field centered on chemical modifications to RNA, has revealed ...

CDX2 downregulation in mouse mural trophectoderm during peri‐implantation is heteronomous, dependent on the YAP‐TEAD pathway and controlled by estrogen‐induced factors

Reproductive Medicine and Biology, 2022
Purpose To investigate the transition of CDX2 expression patterns in mouse trophectoderm (TE) and its regulatory mechanisms during implantation. Methods Mouse E3.5–4.5 blastocysts were used to immunostain CDX2, YAP, TEAD4, and ESRRB.

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.
