FVB和EIIa-Cre小鼠胚胎冷冻保存研究
Zhejiang Journal Animal Science and Veterinary Medicine(2012)
Abstract
为探索FVB和EIIa-Cre小鼠的最佳超排及胚胎冷冻方法,对4~6周龄FVB和EIIa-Cre小鼠进行超数排卵效果比较。结果表明,FVB和EIIa-Cre的超排数量分别为每鼠平均33.71枚和24.23枚,发育至2-细胞期的数量分别为30.43枚和17.08枚,EIIa-Cre的胚胎数明显少于FVB。FVB和EIIa-Cre的胚胎复苏率、妊娠率和产仔率均存在较大差异,分别为77.7%和63.0%、80.0%和57.1%、13.6%和8.2%,FVB小鼠均高于EIIa-Cre小鼠。
