How does the endoplasmic reticulum play a role in blastocyst development and protein synthesis

In technical terms, a blastocyst an embryo in a stage of development when the outer layer of cells has developed into a spherical structure and the inner cells ... The structure of the blastocyst is more complex than earlier embryo stages because as well as increasing in cell number, the cells have become organised into 2 ... A blastocyst transfer is taking an egg fertilized in the lab and implanting it into a woman's uterus when it reaches the blastocyst stage. ... blastocyst is formed. Embryonic stem cells can be derived from this blastocyst to create cell lines that are genetically identical to the donor somatic cell. The major disadvantage of blastocyst transfer is the possibility that no embryos will progress to this stage. This may occur for many reasons, such as an embryo ... A pregnancy goes through several stages of development. A fertilized egg develops into a blastocyst, then an embryo, then a fetus. Category B blastocysts are good quality blastocysts with an elevated ability to implant. Category C refers to blastocysts with an average quality level and ... On day 5, embryos should be reaching the blastocyst stage of development. They are continuing to divide and the number of cells continues to increase. Sep 9, 2015 ... Embryos that exhibit collapse are as likely to hatch as those that do not, but are less likely to implant and should not be replaced if alternatives are ... Sep 16, 2024 ... Blastocyst stage embryo transfers resulted in a similar cumulative live birth rate to cleavage stage embryo transfers in women with at least four embryos ...
