摘要: 为研究亮甲酚蓝(BCB)染色对牛未成熟卵母细胞体外成熟与体外受精(IVM.ⅣF)的影响,在牛卵母细胞成熟培养前用亮甲酚蓝进行染色选择,通过ⅣF检测选择效果。本试验以未进行染色处理的牛卵丘一卵母细胞复合体(COCs)作为对照组,在成熟培养前用26 μmol/L亮甲酚蓝染色90 min作为处理组,将处理组依照胞质的颜色分为蓝色组(BCB+)和无色组(BCB一)。成熟培养后进行体外受精,授精后48 h统计卵裂率,7~8 d后检查囊胚率。结果表明:(1)染色后着色的卵母细胞成熟率(80.83%)与对照组(60.20%)和无色组(51.92%)差异显著(P<0.05);(2)IVF后蓝色组囊胚率(32.99%)较对照组(17.64%)和无色组(3.57%)差异显著(P<0.05)。由此可见,亮甲酚蓝对牛卵母细胞染色的选择被证明可以作为判断卵母细胞质量的一个标记。

Abstract: The aim of this investigation was to study the efect of brilliant cresyl blue(BCB)staining on IVM-IVF in cow.For this purpose,oocytes were stained by BCB and selected by IVF examination before mature culture.COCs without BCB staining was considered as control group,and COCs stained with BCB in 26 μmol/L for 90 min as treatment group before mature culture.Treated oocytes were divided into BCB一(eolourless cytoplasm)and BCB+ (coloured cytoplasm).After
1VM,oocytes were fertilized in vitro(ⅣF).The cleavage rate of eggs at 48 h and the proportion of blastocysts at 8 d after 1VF were compared.The results showed that:(1)The BCB+ oocytes had a signiiicanfly higher proportion of mature rate (80.83%)than control group and BCB—oocytes(60.20% and 51.92%)(P <0.05);(2)The BCB+ooeytes had a signiticanfly higher proportion of blastocysts(32.99%)than control group and BCB-oocytes(17.64% and 3.57%)(P
