Analysis of Germ Cell Function using In Vitro Fertilization

1-All mice were 8�C9 weeks of age.2-Numbers in parentheses represent the percentage of 2-cell embryos as a function of the number of oocytes fertilized3-Embryos were transferred at the 2-cell stage for all IVF experiments. Embryos were transferred to pseudo-pregnant mothers for some but not all IVF experiments.4-The number in parentheses represents the percentage of live birth as a function of the number of embryos transferred.1. 所有实验小鼠均为8~9周龄。 2. 括号内的数值为2细胞胚胎占受精卵母细胞总数的百分比。 3. 所有体外受精（In Vitro Fertilization, IVF）实验均于2细胞阶段开展胚胎移植；仅部分体外受精实验将胚胎移植至假孕受体母鼠。 4. 括号内的数值为移植胚胎数对应的活产率。
