摘要

目的:探讨细胞周期素E（Cyclin-E）在早孕小鼠子宫内膜的的表达及其对小鼠胚胎着床数的影响。方法:应用RT-PCR及免疫组织化学的方法检测早孕小鼠子宫内膜细胞Cyclin-E基因和蛋白的表达规律;观察子宫角注射抗Cyclin-E抗体后对小鼠胚胎着床数的影响。结果:妊娠第1～7d小鼠子宫内膜组织均有Cyclin-E表达

自妊娠2d起表达增强

5d表达量达高峰。小鼠妊娠期Cyclin-E在子宫内膜腔上皮、腺上皮及内膜基质中均有表达。单侧子宫抗Cyclin-E抗体注射后双侧胚胎着床数差值较对照组（注射等体积生理盐水）明显增大。结论:在小鼠胚胎着床过程中

Cyclin-E可能参与调节子宫内膜的增殖分化

在子宫内膜蜕膜化及胚胎着床过程发挥作用。

Abstract

Objective:To investigate the expression rule of Cyclin-E in endometrium during the early pregnancy and its role in blastocyst implantation in mice.Methods:RT-PCR and immunohistochemistry techniques were applied to detect Cyclin-E gene and protein expression in endometrium from pregnant mice on days 1～7.In addition Anti-cyclinE antibody was injected into horns of uterus of day 3 pregnant mice to observe the numbers of implanted blastocysts.Results:Expression of Cyclin-E gene and protein in pregnant mice were steady increasing since day 2 and reaching maximal level on day 5 of pregnancy.Injection of Anti-cyclinE antibody could decrease the numbers of implanted blastocyst compared with that of saline-injected group.Conclusion:Cyclin-E were persistently expressed in mouse endometrium during the early pregnancy and might be concerned with proliferation differentiation of endometrium and participates in the regulation process of mouse blastodyst implantation.
