Popis: | The present study evaluates the effect of different concentrations of antioxidants (catalase - CAT and alpha lipoic acid - ALA) on the follicular activation and morphology, DNA damage, ROS production, and mitochondrial activity in vitrified sheep ovarian tissue.This experiment was divided into two steps. First, ovarian fragments were distributed into the following treatments: fresh tissue or control (CTR), incubation (INC), vitrification without antioxidant (VWA), with CAT (10, 20, or 40 IU mLThe percentage of morphologically normal follicles in vitrified ovarian tissue in the presence of ALA in all concentrations did not differ (p 0.05) from fresh tissue or CTRs. The percentage of activated follicles was higher in ALA100 μM mLAlthough 100 μM/mL of ALA did not alter intracellular ROS, this concentration reduced the levels of ROS in the culture medium, preserved both the follicular morphology, as well as the mitochondrial activity, promoted follicle activation, and protected the follicles from DNA damage. |
