WebAug 1, 2012 · After the embryo reaches the 8-cell stage, the blastomeres begin to show an increase in cell–cell adherence due to the spread of intercellular tight junctions. This is the start of compaction. The process of compaction advances during the next division until the boundaries between the cells are barely detectable ( Veeck, 1999 ). The division of blastomeres from the zygote allows a single fertile cell to continue to cleave and differentiate until a blastocyst forms. The differentiation of the blastomere allows for the development of two distinct cell populations: the inner cell mass, which becomes the precursor to the embryo, and the trophectoderm, which becomes the precursor to the placenta. These precursors typically appear when the blastomere differentiates into the 8- and 16-cell masses.
