“The trophoblast eventually forms the placenta, through which the embryo proper receives dissolved nutrients and is cleansed of waste.”

“A villus has a fibromuscular core with fetal blood vessels and is covered by an epithelium termed the trophoblast.”

“The surface of the sphere is made up of a layer of specialized cells called the trophoblast.”

“In the mammalian embryo, for instance, the first compaction of the blastomeres is under the influence of E-cadherin to produce the trophectoderm.”

“The cells lying between the primitive endoderm and the polar trophectoderm comprise the embryonic ectoderm or epiblast.”

“He created mouse embryos with DNA lacking in CDX2, the gene responsible for forming the trophectoderm, or skin on a blastocyte, which is the early form of an embryo.”

“The placenta derives from embryonic cells called trophoblasts, which form a ball around the cells that ultimately develop into the fetus.”

“Choriocarcinoma is a malignant tumor derived from trophoblasts that has high metastatic potential.”

“Flt-1 is also present on trophoblasts and macrophages, whereas KDR is present on hemopoietic stem cells, megakaryocytes, and retinal cells.”
