At the blastocyst stage, however, sodium pumping on the part of the trophoblast results, through osmosis, in the drawing of water into the blastocoel
, enlarging the blastocyst within the zone pellucida.
These differences are also shown in Figure 4A to E, where the HP or HA exposed groups exhibited embryo developmental morphology, blastocoel
cavity expansion, and embryo quality that were superior to the control.
