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℃.
