| Popis: | The vitrification of zygotes is important for their use as donors for generating genome-edited mice. We previously reported the successful vitrification of mouse zygotes using carboxylated ε-poly-L-lysine (COOH-PLL). However, this vitrification solution contains fetal calf serum (FCS), which contains unknown factors and presents risks of pathogenic viral and microbial contamination. In this study, we examined whether polyvinyl alcohol (PVA) can be used as an alternative to FCS in vitrification solutions for mouse zygotes. When COOH-PLL was added to the vitrification solutions, zygotes vitrified with solutions containing 0.01% PVA (PV0.01) and those vitrified in a control solution containing FCS (75.6%) developed into blastocysts (78.4%). In addition, there were no significant differences in the ability to develop to term between the control solution (46.6%) and PV0.01 (44.1%) groups. In conclusion, we clearly demonstrated that PVA can replace FCS in our vitrification solution supplemented with COOH-PLL for mouse zygotes. |
