对孕36 ~ 38天的马子宫妊娠角灌注原位固定的组织进行光镜和电镜检查，发现马子宫内膜杯由滋养层细胞组成，滋养层细胞起源于被称为绒毛膜带的胎儿膜的离散环状部分。这种结构由细长滋养层细胞的紧密相对的绒毛突起组成，并且在妊娠第36天左右牢固地附着在子宫内膜上。特化的带细胞侵入并吞噬子宫内膜上皮，然后穿过基膜迁移到子宫内膜间质，在那里它们发育成子宫内膜杯细胞。
Light and electron microscopic examination of tissues fixedin situby perfusion of the gravid horn of the uteri of mares between 36 and 38 days of gestation revealed that the equine endometrial cups are composed of trophoblast cells which originate from the discrete annulate portion of the foetal membranes known as the chorionic girdle. This structure consists of closely opposed villous projections of elongated trophoblast cells and it becomes firmly attached to the endometrium around the thirty‐sixth day of pregnancy. The specialized girdle cells invade and phagocytose the endometrial epithelium and then migrate through the basal lamina into the endometrial stroma where they develop into endometrial cup cells.
