Definition of trophoblast in English:

trophoblast

noun ˈtrɒfə(ʊ)blastˈtrəʊfə(ʊ)blastˈtrɑfəblæst

Embryology

A layer of tissue on the outside of a mammalian blastula, supplying the embryo with nourishment and later forming the major part of the placenta.
〔胚〕滋养层
Example sentencesExamples
- A villus has a fibromuscular core with fetal blood vessels and is covered by an epithelium termed the trophoblast.
- When the developing, fertilized egg at the ‘blastocyst’ stage becomes implanted in the lining of the uterus, it develops ‘villi’ - fine, frond-like cellular projections from its outermost layer, the trophoblast.
- The placenta derives from embryonic cells called trophoblasts, which form a ball around the cells that ultimately develop into the fetus.
- The trophoblast eventually forms the placenta, through which the embryo proper receives dissolved nutrients and is cleansed of waste.
- The surface of the sphere is made up of a layer of specialized cells called the trophoblast.

Derivatives

trophoblastic

adjective

Embryology

The vascular endothelium was destroyed by villous proliferation and trophoblastic invasion in this vessel.
Example sentencesExamples
- Nevertheless, one version of this suggestion, the ovarian time bomb hypothesis, explicitly envisages an individual-level cost of parthenogenesis, namely ovarian trophoblastic disease.
- Young women may very rarely develop a malignant trophoblastic tumor, presumably derived from ectopic germ cell tissue.
- Multiple gestation, gestational trophoblastic disease, triploidy, trisomy 21 syndrome, and hydrops fetalis have been associated with an increased incidence of hyperemesis gravidarum.
- We selected principally trophoblastic placental tissue with no signs of calcification, avoiding the decidua basalis and corionic plate.
