Survivability and developmental ability of embryos vitrified and stored in 40% (v/v) ethylene glycol solution containing different concentrations of sucrose at –80°C for 2 days.

The vitrification solutions also contained 18% (w/v) Ficoll.
Embryos in the control group were vitrified and stored in LN2.
Numbers with different superscripts within the same column are significantly different (P<0.05; by Chi-squared test with Yates’ correction).

玻璃化冷冻液中还含有18%（w/v）的Ficoll。
对照组胚胎经玻璃化冷冻处理后，储存于LN2（液态氮）中。
同一列内带有不同上标的数值组间差异具有统计学意义（P<0.05；采用带耶茨校正的卡方检验）。
