摘要 目的探讨在玻璃化冷冻液中添加大分子物质PVP(polyvinyl pyrrolidone)对人卵母细胞冻融效果的影响。方法玻璃化液中添加6%PVP者为A组,不添加者B组,未冻融者为对照组(C组),冻融后存活及对照组卵母细胞固定后进行免疫荧光染色,然后用Nikon CISI激光扫描共聚焦显微镜观察纺锤体、染色体形态。结果 A组的存活率、染色体和纺锤体形态正常率分别为83.3%(20/24)、10.0%(2/20)和10.0%(2/20),B组则分别为95.8%(23/24)、13.0%(3/23)和13.0%(3/23),与对照组比较差异均无统计学意义(P>0.05)。结论在玻璃化液中添加大分子物质PVP没有提高人卵母细胞的冻融效果。
