Fig 1: Increased staining of CCL25 in thymi of E-ARKO mice. Quantification of CCL25-stained area in thymic medulla and cortex of E-ARKO and control mice and mice that were sham-operated or castrated (orchiectomized; ORX) at 4 weeks of age; tissues were collected at 34 weeks of age. Thymic sections were stained for CCL25 (red) and nuclei were stained by 4',6-Diamidino-2-Phenylindole (DAPI; blue). Scale bar = 200 µm. *P < 0.05 vs. control (Mann-Whitney U-test). Bars indicate means, error bars indicate SEM, and circles represent individual mice.
