cytotrophoblastic造句

• There are two lineages that cytotrophoblastic cells may differentiate through : fusion and invasive.
• An undifferentiated cytotrophoblastic stem cell will differentiate into a villous cytotrophoblast, which is what constitutes primary chorionic villi, and will eventually coalesce into villous syncytiotrophoblast.
• The interface between fetal and maternal components of the placenta is rather distinct : the decidua basalis ( maternal ) is separated from the chorionic villi by a cytotrophoblastic shell that is derived from fetal tissue ( the trophoblast ) and is several cells thick.
• HCG secreted by cytotrophoblastic cells of the blastocyst controls endometrial tissue remodeling by both activation of matrix matalloproteinases ( MMP ) that control the maternal extracellular matrix and inhibition of tissue-inhibitors of matrix-metalloproteinases ( TIMP ) . hCG mediates invasion and attachment to the endometrium.
