摘要 本实验探究体外成熟(IVM)培养基中添加不同浓度白藜芦醇(0、0.5、2.0、5.0μmol/L RES)对绵羊卵母细胞核质成熟的影响。IVM 24 h后观察卵丘细胞扩展率和卵母细胞第一极体形成情况,并检测卵母细胞细胞质内活性氧(ROS)和谷胱甘肽(GSH)含量。结果表明:与对照组相比,0.5μmol/L RES组的卵丘细胞扩展率无显著差异,卵母细胞第一极体的形成显著提高,卵母细胞胞质中ROS显著降低,GSH含量显著提高;添加量增至5.0μmol/L卵丘扩展率、第一极体形成率、胞质内GSH含量显著下降。综上所述,在绵羊卵母细胞IVM液中添加0.5μmol/L RES通过降低胞质内ROS及提高GSH含量增强卵母细胞抗氧化能力,提高卵母细胞核成熟率及胞质质量,而促进卵母细胞体外成熟。
