PS-MPs exposure triggers premature testicular aging. a SA-β-Gal staining of testicular tissue. b Quantitative analysis of SA-β-Gal staining as presented in a. c Representative IHA images of p21, p16 and p53 in the testis from control and PS-MPs exposure mice. d-f Quantification of p21, p16, p53-positive cells as shown in c. g, h Representative IHA images depicting Ki67, γ-H2AX and 53BP1 in the testis following PS-MPs treatment. i-k Quantification of Ki67, γ-H2AX and 53BP1-positive cells as described in g, i.
