Photomicrographs of paraffin-embedded sections of normal (B) and experimental (C) adult testes immunostained with Gal-1 antibody. Strong Gal-1 immunoreactivity can be observed within the seminiferous tubules associated with both Sertoli cells (arrow) and differentiating germ cells and also in Leydig cells (arrowhead) located in the interstitial spaces.
