Introduction
Human blastocyst (day 5) still within zone pellucida. |
The free-floating blastocyst has reached the uterine body still enclosed in the zone pellucida and "hatches" from this surrounding extracellular matrix.
It is only after hatching that the blastocyst can attach to and then implant into the uterine wall.
