妊娠相关主基蛋白(pregnancy-associated major basic protein,pMBP)在生殖生理中的作用至今不清。其在母胎交接点X细胞上的定位引发了许多假说,包括可能限制滋养细胞的侵蚀和潜在恶性倾向。但X细胞是否出现在胎盘部位滋养细胞肿瘤或绒毛膜癌中仍有争议。 用放射免疫法测定非妊娠、正常妊娠、部分性葡萄胎、完全性葡萄胎、持续性葡萄胎、胎盘部位滋养 The role of pregnancy-associated major basic protein (pMBP) in reproductive physiology is still unclear. Its location at the maternal-fetal junction X cells elicits many hypotheses, including the potential to limit the erosion of trophoblasts and potentially malignant tendencies. However, whether X cells appear in the placental site of trophoblastic tumor or choriocarcinoma is still controversial.
