滋养层细胞是胚胎与母体直接接触的部分,滋养细胞侵入母体蜕膜后,不被母体排斥而快速增殖是妊娠成功的关键因素之一,同时滋养细胞有节制地侵入子宫内膜基质也是正常妊娠所必需。滋养层细胞生物学功能的异常可能导致自然流产、妊娠高血压疾病及胎儿生长受限等病理妊娠。
Trophoblast cells are the parts of the embryo that are in direct contact with the maternal body. After the trophoblasts invade the decidua of the maternal body and are not repulsed by the maternal body, the rapid proliferation is one of the key factors in the success of pregnancy. At the same time, the trophoblast cells invade the endometrial stroma in a controlled manner is also a normal pregnancy Necessary. Abnormal trophoblast cell biology may lead to pathological pregnancy such as spontaneous abortion, pregnancy-induced hypertension and fetal growth restriction.
