Dual IHC staining of normal human FT at the fimbrial end. The axonemes of MCC and primary cilia are visualized by staining for polyglutamylated tubulin (brown), and MCC were also visualized by staining for DNAH5 (red). Sections were counterstained with hematoxylin. Arrows indicate MCCs, and arrowheads indicate single immotile primary cilia on secretory peg cells. Black symbols indicate MCCs and primary cilia shown in detail for magnified insets. Scale bars = 10 μm.
