摘要:

研究输卵管上皮细胞共培养对小鼠早期胚胎发育的影响,探索输卵管上皮细胞共培养克服胚胎发育阻滞的机理。建立纯化的小鼠输卵管上皮细胞系,并与合子进行共培养,用DCHFDA测定胚胎内部的H2O2含量,以MTT法测定输卵管上皮细胞活力,RT-PCR检测CATGPX的转录状况。输卵管上皮细胞共培养能够显著提高2-细胞早期、4-细胞期胚胎发育率(P0.05),囊胚率也有所提高(P0.05)。输卵管上皮细胞共培养能够显著降低2-细胞早期胚胎内部的H2O2含量(P0.05)。小鼠阻滞胚胎中有H2O2蓄积,输卵管上皮细胞共培养能够降低Ⅰ和Ⅱ型阻滞胚胎的比例(P0.05),显著地提高Ⅲ型阻滞胚胎的比例(P0.05)。当胚胎发育到2-细胞早期时共培养细胞活力上升(P0.05),抗氧化基因CATGPX转录量增加(P0.05)。以上结果表明,输卵管上皮细胞共培养通过细胞-细胞间的相互作用降低胚胎细胞内部的活性氧,克服胚胎发育阻滞,促进胚胎发育,提高胚胎质量。

Abstract:

This experiment was conducted to study the effect of oviduct epithelial cells co-culture on the development of early embryos, and explored the mechanisms of oviduct epithelial cells co-culture on overcoming the developmental arrest in mouse. Mouse oviduct epithelial cell line was purified and used to co-culture the zygotes, H2O2 contents in embryos were measured by DCHFDA, MTT was used to measure the activity of epithelial cells, RT-PCR was applied to test the transcriptions of CAT and GPX genes. Oviduct epithelial cells co-culture can significantly improve the early 2-cell and 4-cell rates (P0.05), the blastocyst rate was also increased (P0.05). Oviduct epithelial cells co-culture can decrease the H2O2 content in early 2-cell embryos (P<0.05). Also there was a deposit of H2O2 in the arrested embryos, the rates of typeand arrested embryos were decreasedP>0.05),type was increasedP0.05by oviduct epithelial cells co-culture. On the other side, the cellular activity was improved (P0.05) when embryos developed to early 2-cell phase, at the same time, transcriptions of CAT and GPX were increasedP>0.05. Those results indicated that oviduct epithelial cell co-culture can improve the development of embryos by cell-cell contact to decrease the reactive oxygen species content in embryos, overcome developmental arrest and promote embryo development.
