为了阐明胚胎着床的机制，我们采用子宫内膜三维重建的方法研究了小鼠胚胎在子宫内的位置与子宫腺体沿子宫角长轴分布的关系。子宫内膜有两个独特的区域。子宫腺从子宫系膜侧向子宫系膜侧广泛分布。在另一种情况下，它从侧面定位到反系膜侧。这些不同的区域在子宫角上交替排列。胚胎的数量和位置与后一区域一致。本研究提示子宫腺的分布类型与小鼠胚胎的位置密切相关。
To clarify the mechanism of implantation, relationship between positioning of the mouse embryo in the uterus and distribution of uterine glands along the long axis of the uterine horn was examined by three-dimensional remodelling of the uterine endometrium. There were two unique regions in the endometrium. Uterine glands were distributed widely from mesometrial to anti-mesometrial side in one region. It was localized from lateral to anti-mesometrial side in another. These different regions were alternately aligned throughout the uterine horn. The number and position of embryos was consistent with that of the latter region. This study suggests that the type of distribution of uterine glands is closely related to the positioning of the embryo in mice.
