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 ...

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 ...

Under the microscope, they looked identical to real early embryos or blastocysts, with the same spherical ball of cells that would usually go on to make the placenta and baby. The researchers were ...

The embryo forms a hollow sphere called a blastocyst, with some cells destined to go on to form the placenta, some the yolk sac and others, ultimately, us. But without OCT4 the blastocyst cannot form.

This self-protective mechanism allows some species of animals, including mammals, to arrest or delay the development of ...

Female age is significantly and directly related to embryo aneuploidy rates. The current delay in motherhood has led to a ...

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 ...

Multiple gestations are the most frequent complications associated with assisted reproductive techniques (ART). To decrease the rate of twin and higher order multiple gestations, the ...

has introduced a novel 3D imaging model designed to identify features of blastocysts – the early stage of development for an implanted embryo – associated with successful pregnancies.
