Effects of Resveratrol on Vitrified Porcine Oocytes

Table 1

Effect of Resveratrol supplementation on exteriorization of phosphatidylserine, assayed by Annexin V/Hoechst 33342/PI staining, in vitrified oocytes. Data are presented as mean percentage.

Group	𝑁 oocytes	% viable oocytes (A− PI−)	% apoptotic oocytes (A+ PI−)	% dead oocytes (PI+)
CTR	310	66.1^a	28.4^a	5.5^a
A	150	78.7^b	15.3^b	6^a
B	124	83.1^b	16.9^b	0^b
C	122	80.3^b	18.9^b	0.8^b
D	114	81.6^b	17.6^b	0.9^b

Different superscripts within the same column indicate significant differences (𝑃<0.05).
CTR: control group; (A) 2 μM R supplementation during IVM; (B) 2 μM R supplementation during the postwarming incubation for 2 h; (C) 2 μM R supplementation during vitrification/warming and 2 h after warming; (D) 2 μM supplementation in all previous steps.
