Influence of Exposure to Benzo[a]pyrene on Mice Testicular Germ Cells during Spermatogenesis
Figure 6
A serial cross section of a seminiferous tubule shows apoptosis in testicular germ cells detected using the TUNEL assay. (a) Control, 400x, no fluorescence indicates no apoptosis in the cells in the testicular tissue; (b) 100 mg/kg/day for 60 days, 400x, fluorescence indicates apoptosis occurring in germ cells, including spermatogonia, pachytene spermatocytes, round spermatids, and elongated spermatids.
