本文应用胚泡移植和改进的内膜上皮细胞与胚泡共培养方法研究了胚胎和子宫内膜不同发育状态对子宫内膜对胚泡接受性的影响.实验证明正常胚泡移植到子宫内膜的“着床窗口”出现时间以妊娠d4天上午9时到下午18时.如果被移植的胚泡是取自延缓着床胚泡,则它们的“着床窗口”出现时间有明显缩短,只能到下午14时为止.另外也证明.子宫内膜本身发育状态对内膜的接受性也有影响.以妊娠d5天内膜的胚泡附着数最多.所以.可以认为胚胎和内膜的发育状态都是可以影响内膜“着床窗口”的出现与消失的.
In this study, blastocyst transfer and modified endometrial epithelial cells co-culture with blastocyst were studied embryos and endometrial different developmental status of endometrial on blastocyst receptivity.Experiments show that normal blastocyst transplanted to the endometrium Of the “implantation window” appear to d4 days of pregnancy 9:00 am to 18:00 pm if the transplanted blastocysts are derived from delayed implantation of blastocysts, their “implantation window” appeared significantly shorter time, only To 14 o’clock in the afternoon.Also proved that the development of the endometrium itself on the endometrial receptivity also affected.D5 days of pregnancy within the membrane blastocyst adhesion number.So we can think of embryonic and endometrial development All can affect the appearance and disappearance of the “implantation window” of the intima.
