摘要: 为了探讨亮甲酚蓝(brilliant cresyl blue,BCB)对牛未成熟卵母细胞染色选择后对其体外成熟(IVM)和凋亡的影响,本研究在牛卵母细胞成熟培养前用26 μmol/L BCB染色90 min作为处理组,以未染色卵母细胞作为对照组;将处理组依照胞质的颜色分为蓝色组(BCB+)和无色组(BCB-),成熟培养后检测卵子的发育能力。结果表明:①经BCB染色卵母细胞在成熟后,BCB+组卵母细胞成熟率(80.92%)较对照组(60.00%)和BCB-组(51.61%)差异显著(P<0.05);②BCB+组的凋亡率(6.50%)较对照组(28.21%)、BCB-组(39.06%)差异显著(P <0.05),随着卵母细胞发育潜能的升高其凋亡率逐渐降低。由此可见,以亮甲酚蓝染色为基础的牛卵丘-卵母细胞复合体的区分可以用来有效的选择更具发育活力的牛卵母细胞。

Abstract: The aim of this investigation was to study the effect of brilliant cresyl blue (BCB) staining on IVM apoptosis in cow, 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-(colourless cytoplasm) and BCB+(coloured cytoplasm). After IVM, to assess the developmental potential of the oocytes. The results showed that, the BCB+ oocytes had a significantly higher proportion of mature rate (80.92%) than control group (60.00%) and BCB-oocytes (51.61%)(P<0.05);The BCB+ oocytes yielded a significantly lower apoptosis rate (6.50%) than that in control (28.21%) and BCB- oocytes (39.06%)(P<0.05). These results suggested that the staining of cow cumulus-oocyte complexes with BCB before in vitro maturation could be used to select developmentally competent oocytes.
