摘要: 对新西兰兔成熟卵母细胞在不同方式激活后的发育潜能和孤雌胚胎在不同培养体系中的发育进行了研究。结果发现电击激活和化学激活单独使用不能很好的激活兔卵母细胞,两次电击和化学激活配合使用能够较好的激活兔卵母细胞。通过比较发现B2培养基支持兔孤雌胚胎发育的能力显著高于其他培养基。试验建立了和体内受精时间过程相似的卵母细胞活化和培养系统,为兔的核移植技术优化了条件。

Abstract: The development potentiality of the matured Newzeland rabbit oocytes that were activated by different ways and cultured in different media was compared. The result is that the electric pulse or chemical activation could not activate the oocytes perfectly when they were used separately, but the combination of electric pulse and chemical activation could activate the oocytes more perfectly. B2 medium is better than other media to support the development of the parthenogenetic rabbit embryos by comparison. The study offered an optimized system for the rabbit oocyte activation and cultures same as fertilization in vivo, which will supply good condition for rabbit nuclear transfer.
