Effects of Resveratrol on Vitrified Porcine Oocytes

Table 2

Effect of Resveratrol on caspase activation in vitrified oocytes, as assayed by FITC-VAD-FMK/Hoechst 33342/PI staining. Data are presented as mean percentage.

Group	𝑁 oocytes	% live oocytes (PI−)		% dead (PI+)
		VAD−	VAD+
CTR	165	81,82^a	10,30^a	7,88^a
A	84	91,67^b	7,14^a	1,19^b
B	76	86,84^ab	9,21^a	3,95^ab
C	75	84,00^ab	13,33^a	2,67^ab
D	91	89,01^ab	7,69^a	3,30^ab

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.
