Embroys implant at endometrium after development in the tube and intra-uterine cavity. So endometrium may play a role of enhancement of embryonic development. In this study, we evaluated the action of endometrium on early embryonic development by using co-culture system with endometrial stromal cells (ESCs) and mice embryos. ESCs were obtained from patients with leiomyoma (control) or endometriosis (EM). ESCs from control increased the embryonic development in comparison with EMS.Peritoneal fluid (PF) from EM suppressed the embryonic development in the co-culture system. Next the influence of serum from EM patients on embryonic development was evaluated. This suppressed the embryonic development. Further, culture of embryo in the culture medium with erythrocytes enhanced the embryonic development. In this studies, co-culture with SMC from control or erytrocytes in culture medium enhanced the embryonic developments and co-culture with stromal cells from EMS and PF or serum from EM suppresed th embryonic development. Now we are studying about enhancing factor from endometrium and suppresing factor PF or serum from EM on embryonic divelopment.

在输卵管和宫腔内发育后，胚胎植入子宫内膜。因此子宫内膜可能起到促进胚胎发育的作用。在本研究中，我们通过使用子宫内膜基质细胞（ESC）和小鼠胚胎的共培养系统评估了子宫内膜对早期胚胎发育的作用。 ESCs 取自平滑肌瘤（对照）或子宫内膜异位症（EM）患者。与 EMS 相比，来自对照的 ESC 增加了胚胎发育。来自 EM 的腹膜液 (PF) 抑制了共培养系统中的胚胎发育。接下来评估了 EM 患者血清对胚胎发育的影响。这抑制了胚胎的发育。此外，在含有红细胞的培养基中培养胚胎增强了胚胎发育。在这项研究中，与来自对照的SMC或培养基中的红细胞共培养增强了胚胎发育，与来自EMS和PF的基质细胞或来自EM的血清共培养抑制了胚胎发育。目前我们正在研究子宫内膜的促进因子和抑制因子PF或EM血清对胚胎发育的影响。
