Abstract
Purpose
This study was conducted on the effects of vitrification cryotop method on gene expression of mature oocytes in Mus musculus.
Methods
Transcript analyses of three mouse genes, namely Mater, Hook1 and Sod1, were performed upon non-vitrified and vitrified oocytes with different concentrations of dimethyl sulfoxide (DMSO) and ethylene glycol (EG),15%: 7.5% DMSO + 7.5% EG, and 30%: 15% DMSO + 15% EG, using cryotop following normalization of transcripts with Hprt1 by nested quantitative PCR.
Results
Vitrification caused down-regulation of Mater and Hook1 and up-regulation of Sod1 when lower concentrations of cryoprotectants were used as opposed to the control group. The relative expression of Sod1 in vit2 (30% v/v) was significantly higher than vit1 (15% v/v). Quantitative transcript analysis of Mater and Hook1 for the vit2 condition failed to produce any data. Survival rates were the same for both vitrification treatments and significantly lower than control group.
Conclusions
Although vit1 treatment had lower survival rate compared to control group, it demonstrated better stability comparing to vit2 based on the transcript analysis.
