Fig. 5From: SF-1 mediates reproductive toxicity induced by Cerium oxide nanoparticles in male miceAO staining result for DNA integrity. The green and red fluorescence indicate the sperm with normal double-stranded DNA and the abnormally denatured DNA, respectively. Arrow shows the sperm head appeared with red fluorescent. Column diagram indicates percentage of red fluorescent labeled sperm in mice exposed to various doses CeO2 NPs. Values are mean ± SD, n = 12. Significance of difference: CeO2 NPs group compared with control, *p < 0.05, **p < 0.01Back to article page
