Fig. 3. Distribution of galectin 1 protein in the adult testis. Sections of Bouin fixed adult mouse testis were stained with Haematoxylin and Eosin (A,C,E) or by anti-galectin 1 alkaline phosphatase immunohistochemistry (B,D,F). (A,B) Galectin 1 immunoreactivity (purple stain) in the wall of a large blood vessel (arrowhead), and interstitial cells (arrows). (C,D) Seminiferous tubules at all stages of the epithelial cycle show strong galectin 1 immunoreactivity in the Sertoli cells, and weaker staining surrounding many germ cell stages. (E,F) Stage VIII tubule with staining of basal and apical regions of the seminiferous epithelium. Groups of round spermatids (asterisks in F) are unstained.
