These are the cells of the embryo that become the placenta and attach the baby to the mother's uterus. These cells provide an armor of protection completely around the baby in the uterus. They also serve to nourish the baby carrying food from the mother's blood to the babies blood. These are the cells that are biopsied during a chorionic villus biopsy (CVS) to determine if the baby is genetically normal.
