The tissue from three tubal pregnancies at the site of implantation has been investigated with light and electron microscopy. Large seemingly "decidual" cells were found to be present between the anchoring villi and the tissue of the uterine tubes. These cells are or cytotrophoblastic column origin. Through discontinuities of the syncytiotrophoblast they migrate into the underlying tissue were they grow and synthesize large amounts of glycogen. It is suggested that these cells be named pseudo-decidual cells in order to distinguish them clearly from genuine decidual cells to which they only bear a resemblance on the light microscopical level. The fibrinoid present at the utero-placental interface in ectopic implantation cannot be found in ectopic implantation. From this fact it is deduced that fibrinoid is formed through the action of genuine decidual cells and therefore must be of maternal origin.
对三个输卵管妊娠着床部位的组织进行了光镜和电镜研究。发现在着床绒毛与输卵管组织之间存在大量看似“蜕膜样”的细胞。这些细胞起源于细胞滋养层柱。它们通过合体滋养层的间断处迁移到下方组织，在那里生长并合成大量糖原。建议将这些细胞命名为假蜕膜细胞，以便将它们与真正的蜕膜细胞清楚地区分开来，在光镜水平上它们只是与真正的蜕膜细胞相似。在异位妊娠的子宫 - 胎盘界面不存在类纤维蛋白。由此推断，类纤维蛋白是通过真正的蜕膜细胞的作用形成的，因此一定是母体来源的。
