A blastocyst is a cellular mass that forms early in the process of embryo development in mammals. In humans, this stage of embryogenesis occurs five days after fertilization, when there are fewer than 100 cells in the mass. At this stage of development, the embryo has not yet implanted in the uterus.
Development of the Blastocyst. Between 5 and 8 days after fertilization, the blastocyst attaches to the lining of the uterus, usually near the top. This process, called implantation, is completed by day 9 or 10. The wall of the blastocyst is one cell thick except in one area, where it is three to four cells thick.
