摘要: [摘要]〓
〖HTH〗目的〖HTSS〗〖KG*2〗检测骨形态发生蛋白9(bone morphogenetic protein9,BMP9)在人卵巢颗粒细胞中的表达水平,探讨其与卵母细胞及胚胎质量的关系。
〖HTH〗方法〖HTSS〗〖KG*2〗收集85例因输卵管因素行常规体外受精-胚胎移植(in vitro fertilization and embryo transfer,IVFET)患者的颗粒细胞,采用免疫细胞化学法、逆转录PCR和Western blot检测颗粒细胞中BMP9的表达。
〖HTH〗结果〖HTSS〗〖KG*2〗BMP9表达于颗粒细胞胞浆中,呈棕黄色颗粒。颗粒细胞中BMP9 mRNA表达与蛋白表达呈正相关(r=0.220,P<005)。BMP9 mRNA及蛋白的表达与患者临床数据及实验室相关数据均无直线相关关系。根据BMP9 mRNA相对表达量的均数将患者分为低表达组和高表达组,高表达组的优质胚胎率、卵子利用率均高于低表达组,差异有统计学意义(P<005)。
〖HTH〗结论〖HTSS〗〖KG*2〗BMP9表达于人卵巢颗粒细胞胞浆内,BMP9高表达可提高优质胚胎率,其表达水平在一定程度上可反映卵母细胞的质量。BMP9可能作为自分泌/旁分泌因子参与生殖系统调控。

Abstract: 〗[Abstract]〓Objective〖HTSS〗〓To detect the expression level of bone morphogenetic protein9(BMP9) in human ovarian granulosa cells, and to discuss its relationship to the maturation of oocyte and development of embryo.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Eightyfive cases were collected from the patients taking in vitro fertilization(IVF) with fallopian tube factor. The expression of BMP9 in granulosa cells were measured by immunocytochemistry, RTPCR and Western blot.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓BMP9 was expressed in the cytoplasm of granulosa cells. There are positive correlation between BMP9 mRNA expression and protein expression in granular cells(r=0.220,P<005). The expression of BMP9 mRNA and protein in granulosa cells do not have linear correlation with clinical and laboratory IVF data. According to the mean of relative expression of BMP9 mRNA, the patients were divided into low expression group and high expression group. High quality embryos and egg utilization in high expression group were significantly higher than those in low expression group(P<005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓BMP9 expressed in the cytoplasm of human ovarian granulosa cells. High expression of BMP9 can increase the rate of high quality embryos, and its expression level in a certain extent can reflect the quality of oocytes. BMP9 may act as an autocrine/paracrine factor involved in the regulation of the reproductive system.
