Vitrification of Mouse Morulae

마우스 상실배의 Vitrification에 관한 연구

In vitro survival of the mouse morulae frozen by vitrification method(Kasai et al., 1990) was investigated in the present study. The embryos were plunged into LN2 directly after exposure to the vitrification solutions(EFS, GFS and DFS). The results were obtained as follows. The viability of morulae after freezing and thawing was high in EFS(96.7∼100.0%) and GFS vitrification solution(93.3∼96.7%), and the lowest in DFS vitrification solution(0.00∼0.03%).
