Peg3 showed completely unmethylated in two cell embryos, and was strongly de novo methylated in morula stages.

结果显示，在正常发育胚胎中，Peg3甲基化印迹在小鼠2细胞胚胎之前就已经被擦除，直到桑椹胚时才被重新建立起来。

At the same time, a fertilized ovum to the uterine cavity gradually moving ,3-4 days after the arrival of intrauterine growth when cells become more than an entity, shaped like mulberry, so called morula.

与此同时，受精卵逐渐向宫腔方向移动，3—4天后到达宫腔时已发育成为一个具有多个细胞的实体，形状象桑椹，所以称为桑椹胚。
