为了明确胎儿输卵管上皮细胞纤毛发育的特征,应用扫描电子显微镜测试系统对孕周16周至36周的33例女性胎儿输卵管上皮细胞进行了定量研究,结果发现:妊娠16周胎儿输卵管上皮细胞已有纤毛发育,峡部纤毛平均高度随孕周增加逐渐增高;壶腹部纤毛平均高度在妊娠20周时出现明显增高;伞部纤毛高度在孕20周及孕32周时出现两次明显增高。表明胎儿输卵管上皮细胞发育过程中纤毛高度变化具有明显的部位异常和阶段性。
In order to clarify the characteristics of fetal oviduct epithelial cell cilia development, the use of scanning electron microscopy test system for gestational age 16 weeks to 36 weeks of 33 cases of female fetus epithelial cells were quantitative analysis showed that: 16 weeks of pregnancy fetal oviduct epithelial cells have cilia The average height of cilia of isthmus increased gradually with the increase of gestational age. The average height of cilia in ampulla increased significantly at 20 weeks of gestation. The height of cilia of umbrella increased significantly twice at 20 weeks of gestation and 32 weeks of gestation. That the fetal oviduct epithelial cells during the development of cilia height changes with significant site abnormalities and stage.
