Melatonin Protects Goat Spermatogonial Stem Cells against Oxidative Damage during Cryopreservation by Improving Antioxidant Capacity and Inhibiting Mitochondrial Apoptosis Pathway

Figure 5

Effects of different melatonin concentrations on the reactive oxygen species (ROS) level of spermatogonial stem cells (SSCs) during cryopreservation. (a) Intracellular ROS fluorescence. The red and white arrows indicate higher and lower ROS levels, respectively. (b) Intracellular ROS content in different groups. Different superscript letters (A–D) indicate significant differences (). Values are expressed as the (). .
