The method of vitrification cryopreservation of mouse 2-cell embryos was studied. Several vitrification solutions named EFS30, EFS40, EDFS30 and EDFS40 were prepared. The solution contains ethylene glycol, Ficoll, sucrose and DMSO. Straw method was used to vitrify and cryopreservate in vivo mouse 2-cell embryos at room temperature (20℃ or 25℃). OPS method was used to vitrify the embryo at 25 ℃ or 37℃.

本试验以毒性低、渗透性较强的乙二醇和DMSO为主体，添加聚蔗糖、蔗糖配制的玻璃化溶液(EFS30、EFS40、EDFS30和EDFS40)，在室温(20℃和25℃)下利用细管法，以及在25℃和37℃恒温台条件下OPS法对小鼠2-细胞胚胎进行玻璃化冷冻保存，并对解冻后胚胎的体外培养、囊胚细胞计数及胚胎移植技术进行了研究。

Subsequently,with the straw and the cell freezing tube,we usedone-step and two-step method to vitrify the embryo of Lats gene knockout mice.The development ratio reached 90% 90.1 % 89.2%, 91.4% and the implantation rauo reached 50.0%, 47.1% 43.4%, 46.5% respectively after thaw.

在此基础上，用冷冻麦管、细胞冷冻管分别采用一步法、二步法对Lats基因敲除小鼠胚胎进行玻璃化冷冻，胚胎解冻后，囊胚发育率分别为：90％、90.1％、89.2％、91.4％；移植后着床率分别：50.0％、47.1％、43.4％、46.5％，差异不显著；并且与对照组相比差异也不显著。
