WebbThe blastocyst remains in the uterus for 2-5 days before implantation. The trophoblast cells secrete enzymes that break down the epithelium of the endometrium. The blastocyst becomes embedded in the endometrium. As the blastocysts develops, the trophoblast forms membranes around the embryo called the chorion (outermost membrane) The … The trophoblast (from Greek trephein: to feed; and blastos: germinator) is the outer layer of cells of the blastocyst. Trophoblasts are present four days after fertilization in humans. They provide nutrients to the embryo and develop into a large part of the placenta. They form during the first stage of pregnancy and are the first cells to differentiate from the fertilized egg to become extraembryonic st…
