About this work


A human embryo at the blastocyst stage, about six days after fertilization, viewed under a light microscope. The embryo is in the process of "hatching" out of the zona pellucida - the tough outer membrane - just before implanting in the wall of the uterus. The actual size of the embryo is about 0.3 mm.
