摘要
目的：观察着床前小鼠子宫及胚卯白细胞介素8（IL-8）的表达。方法：免疫组织化学显色及图像分析技术，对IL-8蛋白在妊娠1～4d小鼠子宫及胚卵的表达进行定位及半定量分析；用RT-PCR技术检测妊娠1～4d小鼠子宫及胚卵IL-8mRNA的表达情况。结果：与未孕小鼠相比，妊娠各天小鼠子宫中IL-8蛋白和mRNA表达明显升高，于妊娠4d表达最强。IL-8蛋白和mRNA均在妊娠2d（II细胞期）的胚卵表达最弱，妊娠4d（胚泡期）的胚卵表达最强。结论：妊娠1～4d小鼠子宫及胚卵持续表达IL-8蛋白和mRNA，尤其是在着床前表达量升高，提示它们可能参与小鼠胚泡的着床过程。
Objective： To study the expression of interleukin-8 （IL-8） in the mouse uterus and embryo during preimplantation. Methods： The mRNA and protein expressions of IL-18 in uterus and embryo of mouse from pregnant day 1 to day 4 were detected by RT-PCR and immunohistochemistry, respectively. Results： Compared to non-pregnant mice, the mRNA and protein expressions of Ibl8 in uterus of pregnant mice were significant up-regulated, and up to peak at pregnant day 4. Additionally, expression of IL-18 protein and mRNA was weak on day 2 （2-cell stage）, and strongest on day 4 （blastocyst stage）. Conclusion： IL-8 protein and IL-8 mRNA are expressed persistently in mouse uterus and embryo on day 1-4 of pregnancy, especially increase in preimplantation. It suggests that IL-8 could participate in the process of blastocyst implantation in mouse.
