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

结果表明：利用电融合方法制备的小鼠四倍体胚胎在体外培养体系中经历细胞质融合、细胞核融合及细胞继续分裂发育直到囊胚期的过程，在细胞质融合的时候胚胎卵裂球同体内体外培养二倍体胚胎一样，呈现高度甲基化状态；在细胞核开始融合的时候，甲基化水平急速下降，在细胞核完全融合的时候甲基化水平达到最低点；随着胚胎继续分裂，胚胎甲基化水平逐渐增加，在囊胚期甲基化水平最高；但是囊胚期四倍体胚胎内细胞团同滋养层细胞甲基化荧光信号没有差别，这与体内体外培养二倍体囊胚内细胞团细胞甲基化荧光强度高于滋养层细胞甲基化荧光强度不同。

The Prince ss never went on sale in Australia , and we are not sure how many were to be sold in the UK , but think this could well be a very collectable car in years to come , if only for its sheer quirkiness .

However, I was so Enamour'd of this Place, that I spent much of my Time there, for the whole remaining Part of the Month of July; and tho' upon second Thoughts I resolv'd as above, not to remove, yet I built me a little kind of a Bower, and surrounded it at a Distance with a strong Fence, being a double Hedge, as high as I could reach, well stak'd, and fill'd between with Brushwood; and here I lay very secure, sometimes two or three Nights together, always going over it with a Ladder, as before; so that I fancy'd now I had my Country-House, and my Sea-Coast-House: And this Work took me up to the Beginning of August.

第二天，十九日，我带着事先做好的两只小袋子回去装运我的收获物。但是，当我来到葡萄堆前面时，原来饱满完好的葡萄，现在都东一片，西一片被拖散开，有的被践踏得破碎不堪，有的则已吃掉了。眼前的情景一片狼籍。这不禁使我大吃一惊。看来，附近一定有野兽出没；至于什么野兽，当然我无法知道。
