Blastocyst compaction
WebThe mouse has been used as a model of preimplantation development for over 45 years due to its similarities to the human embryo [1]. Within 72 h in stable culture conditions mouse embryos develop from one cell to a blastocyst containing at least 32 cells. During that time, cells undergo rapid changes in shape and position resulting in the first ... The blastocyst stage occurs between 5 and 9 days after conception. During embryonic development, after fertilization (approximately 5–6 days in the human), the cells of the morula begin to undergo cell differentiation, and the morula changes into the blastocyst. In the uterus the zona pellucida surrounding the blastocyst breaks down, allowing it to implant into the uterine wall. Implantatio…
