HEMATOLOGY

Three renal epithelial cells, whose nuclei are approximately the same size as an adjacent neutrophil. Renal epithelial cells are polyhedral and columnar. Their nuclei are often slightly off center and displaced towards the cell base. A microvillus border is evident in the cells shown here

L: Transitional epithelial cells, which are nearly spheric due to absorption of water and have large, central nuclei

R: Transitional epithelial cells in urinary sediment. This relief image clarifies spheric shape of these cells and nuclear detail and is superior to ordinary brightfield microscopy for this purpose

Four transitional epithelial cells (center). Although there is much amorphous crystalline material in the field, the cells are still easily recognized. Two are “tadpole”-shaped, whereas the other two are spheric

L: Squamous epithelial cells, commonly seen in clumps, but also singly. They are large, flat, and often have finely wrinkled cytoplasm

R: Group of squamous epithelial cells with mucus strands in the background. Here, the difference between phase-contrast and brightfield microscopy is demonstrated
