Cryopreservation of mammalian zygotes can be advantageous since it enables their flexile use in time and space for alternative purposes such as genome editing. Here we report a simple, quick and inexpensive vitrification protocol for in vitro produced bovine zygotes which enables their bulk preservation. Slaughterhouse-derived oocytes were subjected to in vitro maturation and fertilization (IVF). Ten h after IVF, cumulus-enclosed zygotes were equilibrated in 2% (v/v) ethylene glycol + 2% (v/v) propylene glycol for 13-15 min then vitrified in groups of 52-100 in 2 μL microdrops of 17.5% (v/v) ethylene glycol + 17.5% (v/v) propylene glycol supplemented with 0.3 M sucrose and 50 mg/mL polyvinylpyrrolidone. The presence of cumulus cells is important for the success of the process. Therefore, we applied a modified IVF protocol using a short (30 min) co-incubation interval which allowed zygote culture with attached cumulus cells until vitrification and even reduced polyspermy rates without affecting the total fertilization rate. Vitrified zygotes were similar to their non-vitrified counterparts in terms of survival, post-warming development to the blastocyst stage and blastocyst quality measured by cell numbers and cryo-survival. In conclusion, our vitrification protocol integrated with the modified IVF system enabled the quick cryopreservation of bovine zygotes in large groups without reducing their developmental competence to the blastocyst stage.
