Transmission electron micrograph (TEM) of the ultrastructure of the basal region of the seminiferous epithelium of the testis. Three Sertoli cell nuclei with nucleoli lie close to the basal lamina. Tight junctions occur between adjacent Sertoli cells which serve as the blood-testis barrier. Above and between the Sertoli cells are three zygotene primary spermatocytes displaying round nuclei with condensed chromosomes. Part of a large pachytene primary spermatocyte is seen at upper left.
