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 ...

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.

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.

Gene expression analysis of bovine embryonic disc, trophoblast and parietal hypoblast at the start of gastrulation [PDF]
, 2017 In cattle early gastrulation-stage embryos (Stage 5), four tissues can be discerned: (i) the top layer of the embryonic disc consisting of embryonic ectoderm (EmE); (ii) the bottom layer of the disc consisting of mesoderm, endoderm and visceral hypoblast

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 ...

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.

Equine Veterinary Journal, EarlyView.Abstract Background The success of in vitro embryo production (IVEP) is influenced by donor mare and stallion. Objectives To determine whether donor mare and stallion influence the pregnancy rate after transfer of in vitro produced (IVP) blastocysts and to identify factors influencing the likelihood of obtaining one or more pregnancies from a single ...

Adhesive and degradative properties of human placental cytotrophoblast cells in vitro. [PDF]
, 1989 Human fetal development depends on the embryo rapidly gaining access to the maternal circulation. The trophoblast cells that form the fetal portion of the human placenta have solved this problem by transiently exhibiting certain tumor-like properties ...

Head &Neck, EarlyView.ABSTRACT Background Salivary gland carcinomas are uncommon malignancies with various histological subtypes harboring fusion genes. The EWSR1::ATF1 fusion gene, resulting from a translocation between chromosomes 12 and 22, is frequently observed in hyalinizing clear cell carcinoma (HCCC). However, the role of this fusion gene in HCCC oncogenesis remains
