As shown in Table 1, significantly more embryos developed to the morula/blastocyst and blastocyst stage when vitrified within the cryoloop compared to those vitrified using OPS. Significantly ...

引言我们生命的起点，始于精子与卵子结合形成受精卵（zygote），随后在短短几天内经历一系列精密调控的分裂与分化，最终发展成具有多种细胞类型的囊胚（blastocyst），为胚胎成功植入子宫做好准备。然而，即便在最理想的生殖条件下，仍有大量受精卵无法 ...

Finally, there are ES cells, derived from the inner cell mass of blastocyst-stage embryos. These pluripotent cells are the most ubiquitous of all. Once removed from the blastocyst they lack the ...

Stem cell-based embryo models, such as blastoids, serve as models of the blastocyst and are invaluable tools for studying embryogenesis and early human development. However, the variability in ...

Should it be a baby in the eye of the law? After the blastocyst has grown comes the hard part. Embryos must survive their cryogenic thaw. One must successfully implant in the walls of a uterus ...

As division continues, some cells divide into the growing mass, distinguishing cells that form the embryo (epiblast) from those that form the placenta (trophectoderm). Further cell divisions lead to ...

blastocyst culture, and/or cryoconservation), namely, a very early, complete division/duplication of the embryo, so that monozygotic twins each have their own placenta and their own membranous ...
