  • Title: [Effect of human oviductal embryotrophic factors on gene expression of mouse preimplantation embryos].
    Author: Yao YQ, Lee KF, Xu JS, Ho PC, Yeung SB.
    Journal: Zhonghua Fu Chan Ke Za Zhi; 2007 Sep; 42(9):605-7. PubMed ID: 17983515.
    Abstract:
    OBJECTIVE: To investigate the effect of embryotrophic factors (ETF) from human oviductal cells on gene expression of mouse early developmental embryos and discuss the role of fallopian tube in early development of embryos. METHODS: ETF was isolated from conditioned medium of human oviductal cell line by sequential liquid chromatographic systems. Mouse embryos were treated by ETF in vitro. Using differential display RT-PCR, the gene expression of embryos treated by ETF was compared with embryos without ETF treatment. The differentially expressed genes were separated, re-amplified, cloned and sequenced. RESULTS: Gene expression profiles of embryos with ETF treatment was different from embryos without this treatment. Eight differentially expressed genes were cloned and sequenced. These genes functioned in RNA degradation, synthesis, splicing, protein trafficking, cellular differentiation and embryo development. CONCLUSION: Embryotrophic factors from human oviductal cells affect gene expression of early developmental embryos. The human oviductal cells play wide roles in early developmental stages of embryos.
