title: Wandering cells in the nephron of the mudskipper Periophthalmus koelreuteri (Pallas).
abstract: Wandering cells that infiltrate between the principal cells of the nephron of the mudskipper Periophthalmus koelreuteri were examined by transmission electron microscope. These cells were found at various levels between the tubule cells and were more abundant in the proximal and collecting segments. These cells have cytoplasmic processes and large spherical nuclei. Their cytoplasm appears electron dense and contains many lysosomes, rough endoplasmic reticulum, free ribosomes, some mitochondria and Golgi profiles. Their ultrastructural features indicate that they may be phagocytic.
