Figure 7. Lack of effect of Esr1 gene disruption in testes of adult male mice. (A) Quantitative analysis of Stra8 mRNA levels in testes of wild type (WT) and Esr1–/–mice at 3 months of age (mean ± SEM; n = 3 mice per group). (B, C) Histological appearance of the testes of WT (B) and Esr1–/– (C) mice at 3 months of age, after fixation and analysis by immunohistochemistry for Stra8 expression (brown immunoreaction product against a blue hematoxylin counterstain).
