β-galactosidase Expression Activated by FVB/EIIa-cre in Adult Testis

Adult testis and epididymus
A. Adult (8 weeks) testis and epididymis at 2x magnification showing strong β-gal expression scattered throughout the epithelium of the epididymis and very weak β-gal expression in the tubules and interstitial cells of the testes.  
Adult testis, closeup of weak staining
B. Adult (8 weeks) testis at 10x magnification (from the same section as B) showing limited staining in both the seminiferous tubules and interstitial cells.
Adult epididymus, higher magnification
C. Adult (8 weeks) epididymis at 20x magnification showing strong β-gal expression in the epithilium.
Additional tissues showing β-gal expression activated by FVB/EIIa-cre.
