Figure 3. HT-2 toxin exposure causes oxidative stress in porcine oocytes.

(A) Oocytes were stained with DCHFDA to detect intracellular reactive oxygen species (ROS) levels at the MI stage. ROS level was significantly increased after exposure to HT-2 toxin. Bar = 20 μm. (B) Average ROS fluorescence intensity in porcine oocytes. The ROS fluorescence intensity was increased significantly after HT-2 treatment. *p < 0.05. Bar = 20 μm.
