The effect of resveratrol on the developmental competence of feline oocytes vitrified at the metaphase II stage
The objective of this research was to assess the viability and developmental potential of feline oocytes following in vitro maturation (IVM), vitrification, and post-warming incubation with resveratrol. In the first experiment, warmed oocytes were incubated with 0.2 μM, 2 μM, or 20 μM resveratrol for 2 h. Oocytes treated with 0.2 μM resveratrol had the highest viability (68.89 %), as assessed by fluorescein diacetate and ethidium bromide staining, while higher concentrations were associated with diminished oocyte viability. In the second experiment, the warmed oocytes were inseminated following the 2-h incubation with the three concentrations of resveratrol. The presumptive zygotes were then maintained in culture and their development evaluated. The highest cleavage rate was observed when the oocytes had been incubated with 0.2 μM resveratrol (88.34 %), which was higher than for the control group (without resveratrol (75 %)). Moreover, this concentration of resveratrol also augmented the blastocyst formation rate. While the vitrification of oocytes often results in diminished developmental potential in the ensuing embryos, attributed to cryopreservation-induced injury, the utilization of low concentrations of resveratrol enhances the procedure's efficacy.
