Pronounced senescence in aged boar testes. (A) The histological analysis of testicular tissue from pigs of different ages. 1-day-old (D1), 60-days-old (D60), 150-days-old (D150), and aged boars (over 5 years old), scale = 50 μm. (B) SA-β-gal staining indicating cellular senescence in Sertoli cells and most LCs of aged boars. Pink represents the nucleus; blue indicates SA-β-gal staining. Scale bar = 100 μm. (C) Accumulation of reactive oxygen species (ROS) observed in all testicular cells of aged boars. Blue represents the nucleus; red indicates ROS. Scale bar = 100 μm.
