Immunohistochemistry (IHC) analysis of testis cross-sections revealed specific expression patterns among various cell types. (A1-A4) PLZF-positive cells (red) exhibited no expression for the germ cell marker VASA (green). (B1-B4) SOX9-positive cells (green) were negative for the germ cell marker DAZL (red) (Scale bar = 50 µm)
