The prevalence of aneuploid cells in miscarried human embryos is higher than previously quoted. Genomic imbalances seem to be less tolerated in the embryoblast than the trophoblast, which indicates that allocation of aneuploid cells to the inner cell mass during blastocyst formation might have a detri...
These transitory cavities are interpreted as rudimentary head cavities, homologous with the premandibular head cavities of marsupials, birds, reptiles and elasmobranchs. The pre-mandibular condensations in which the head cavities of the human embryo briefly appear, ultimately give rise to the extrinsic ...
Despite its basic and clinical importance, human embryo development from peri-implantation to gastrulation remains shrouded in mystery. Recent advances in the elongated in vitro culture of rodent and non-primate embryos and the construction of embryo-like structures have helped to improve understanding ...
The morphology of the developing lateral pterygoid muscle and its relationships with the temporomandibular joint disc and Meckel's cartilage were studied in 16 human embryos and fetuses ranging in age from 5 weeks to 14 weeks. All the temporomandibular joint structures and the lateral pterygoid muscle...
secreteshuman chorionic gonadotropin (hCG), a hormone that directs the corpus luteum to survive, enlarge, and continue producing progesterone and estrogen to suppress menses. These functions of hCG are necessary for creating an environment suitable for the developing embryo. As a result of this ...
Low expression of p53 is also essential for the early development of human embryo, while abnormal activation of p53 could inhibit blastocyst formation and lead to embryo demise9. Whether HUWE1 plays an important role in the development of preimplantation embryo remains unclear. In this study, ...
Human zygotes resulting from IVF were placed in two different culture systems to evaluate in-vitro development and to establish pregnancies in patients following embryo replacement. Treatment A (control) consisted of culturing zygotes in a modified Earle's Balanced Salt solution while treatment B cons...
To comprehensively determine the genetic characteristics of human embryos through development, we performed single-cell sequencing at distinct stages: at the whole-embryo scale in the blastocyst stage, and single-cell RNA-sequencing (scRNA-seq) analysis of embryos at day 8–14 (in vitro cultured) ...
