摘要 目的探讨去透明带方法的选择对小鼠早期胚胎体外培养的影响。方法用孕马血清促性腺激素(PMSG)与人绒毛促性腺激素(hCG)对小鼠进行超数排卵后,取单细胞阶段受精卵,将其分为酸性台式液去透明带组(台式液组)、0.5%链霉蛋白酶去透明带组(链霉蛋白酶组)以及未去透明带组。体外培养,分别观察三组单细胞受精卵分裂为2-细胞受精卵的卵裂率。结果台式液组、链霉蛋白酶组与未去透明带组的第一次卵裂率分别为65.1%、66.7%、66.1%,三组之间比较差异无统计学意义(0.950>P>0.900)。结论在体外培养条件下,用酸性台式液去透明带与0.5%链霉蛋白酶去透明带后受精卵均能进行正常分裂,此两种处理方法对受精卵早期发育均没有影响。
