... and human. Adhesion Blastocyst Endometrium Epithelium Trophoblast Implantation is the stage of pregnancy at which stable adhesion is initiated between the embryo and maternal tissue. Blastocyst-stage embryos hatch from the zona pellucida, exposing trophectoderm – which forms the primary...

... mosaic mice through the injection of wild-type (WT) embryonic stem cells (ESCs) into SGδ-knockout (KO) blastocysts. ESC-derived SGδ was supplied to the sarcolemma of 18-month-old chimeric muscle, which resulted in the restoration of the SGC. Despite SGC rescue, and contrary to previous observations...

... Cζ (PKCζ) and PKCδ are also found, indicating a role in cell surface reorganization and polarization. Subsequently, in morulae and blastocysts, JAM-1 is distributed ubiquitously at cell contact sites within the embryo but is concentrated within the trophectoderm apicolateral junctional complex...

... associated in decidualizing stromal cells of the primary decidual zone forming a barrier surrounding the embryo with the loss of adjacent luminal epithelium. The blastocyst trophectoderm appears to be the stimulus for the creation of this barrier, since isolated inner cell mass or artificial stimuli failed...

... ES and EG cell lines from the human blastocyst and embryonic gonad can differentiate into multiple types of somatic cell. The phenotype of the blastocyst-derived cell lines is very similar to that of monkey ES cells and pluripotent human embryonal carcinoma cells, but differs from that of mouse ES...

...M. Thomas; S. Jain; G. P. Kumar; M. Laloraya ABSTRACT The emergence of the mammalian blastocysts from their thick glycoprotein investment known as the zona pellucida is an important, but poorly understood, event in embryogenesis. In this paper, we demonstrate that peri-hatching blastocysts generate...

...Tom P. Fleming; Qamar Javed; Jane Collins; Mark Hay ABSTRACT The preimplantation embryo differentiates the trophec-toderm epithelium which, from the 32-cell stage, generates the blastocoel of the blastocyst and, after implantation, gives rise to most extraembryonic lineages of the conceptus...
