人类的子宫内膜间质细胞是一种具有高度分化能力的幼稚间叶细胞。在月经周期中它可以向两个方向分化,一种分化为前蜕膜细胞,胚胎植入后进一步发育成蜕膜细胞。另一种即子宫内膜颗粒细胞。虽然早年已有人注意到这种胞浆内含有颗粒的细胞,但由于它的形态与子宫内膜间质中某些细胞成份相似及在普通染色中不能很好地显示其特征,因此将它与其它细胞混淆,命名不一, Human endometrial stromal cells are a type of highly differentiated naive mesenchymal cells. In the menstrual cycle, it can differentiate into two directions, one that differentiates into pre-decidual cells and further develops into decidual cells after implantation. The other is endometrial granulosa cells. Although this intracytoplasmic particle-containing cell has been noticed in the early years, its shape is similar to that of some cellular components in the endometrial stroma and its character is not well represented in normal staining, Other cells confused, different names,
