摘要 目的探讨体内、外受精对小鼠胚胎发育及囊胚孵出率的影响,为鼠胚试验在人类体外受精(IVF)胚胎实验室质量控制中的应用提供依据。方法将超排后的雌性昆明小白鼠随机分为2组,A组与雄性小鼠交配,D1获取体内受精卵;B组直接获取卵子,通过体外受精获得受精卵。分别将这2种受精卵体外培养至第5d,观察其卵裂率、囊胚形成率的差异;以及对囊胚进行玻璃化冷冻复苏,比较囊胚冷冻与否孵出率的差异。结果小鼠体内、外受精卵的卵裂率(72.1%vs 68.8%,P>0.05)、囊胚形成率(79.2%vs 75.4%,P>0.05)均无显著差异;囊胚冷冻与否孵出率差异不显著(75.1%、72.7%,P>0.05)。结论两种不同来源的昆明小白鼠胚胎培养方法均可用于新建胚胎实验室的质量控制。成熟的玻璃化冷冻技术可用于新建胚胎实验室的质控。
