Nettet25. jul. 2024 · In mice, previous studies have shown that the state of activity of the blastocyst is a determining factor in initiating implantation in the receptive uterus ( 4 ). In fact, the blastocyst functions as an active unit with distinct molecular programs of cell growth and differentiation during implantation. Nettet16. jul. 2015 · The blastocyst genotyping approach is flexible and can be used for all kinds of mutations including those generated by recent genome editing techniques such as Crispr/Cas9 that can be discriminated by one or a limited number of PCR reactions (the DNA extracted from a blastocyst is sufficient for 2–3 PCR reactions).

NettetMouse blastomeres are considered totipotent until the 8-cell stage (. ). The blastomeres then compact, polarize, and undergo the first two lineage segregations to generate three different cell types of a blastocyst. The first lineage segregation specifies an outer trophectoderm (TE) layer and an inner cell mass (ICM).
