Tetraploid embryos could be produced by electrofusion at the stage of two-cell embryos, which could develop to blastocysts followed by fusion of cytoplasm and nucleus and cleavage in vitro. During the fusion of cytoplasm, the DNA methylation levels of the fused embryos are as high as these of two-cell diploid embryos in vivo Then the embryos are rapidly demethylated when the nucleus begin to fuse, resulting in the lowest DNA methylation levels when the nucleus are fused completely. After that, the DNA methylation levels of the fused embryos are gradually increased until the morula stage. However, whereas an asymmetric distribution of DNA methylation is established in vivo-derived blastocysts with a higher methylation level in the inner cell mass than that in the trophectoderm, we can not detect the asymmetric distribution in most in vitro-derived tetraploid blastocysts.

blastocyst：胚泡

桑葚胚進入子宮后不久,分裂成由32-64個細胞組成的早期囊胚(blastula)或稱為胚泡(blastocyst), 開始出現(xiàn)腔隙,稱為囊胚腔. 囊胚腔由一層細胞組成,稱為滋養(yǎng)外胚層(trophectoderm), 一端為內(nèi)細胞團(inner cell mass , MASS),

morula：桑葚胚

受精卵在從輸卵管向子宮運行的過程中不斷進行卵裂,當分裂到8-16個細胞時為一實心球體,稱為"桑葚胚"(morula),此時每個卵裂球仍保持這種全能性,都可以發(fā)展成為一個完整的個體.
