It is composed of 3 types of cells: (1) the basal cells, which are cylindrical to flat and in contact with the underlying fibroconnective tissue or lamina propria--the basal cell layer is thought to harbor urothelial stem cells; (2) the intermediate cells, which are cuboidal
to columnar cells, overlie the basal cells, and usually have the same orientation toward the bladder lumen; and (3) the umbrella cells, which are larger flat eosinophilic cells, with ample pink cytoplasm and variable nuclear reactive/degenerative atypia such as binucleation, smudging, and nucleoli.
Histologic findings are cysts of variable size lined by flattened or cuboidal
mesothelial cells, sometimes with a "picket-fence" or "hobnail" appearance (Figure 5, C).
Cells may vary between ciliated or nonciliated and columnar or low cuboidal
, as was seen in all 3 cases presented here.
In addition, the papillae in well-differentiated mesotheliomas of the tunica vaginalis testis are typically lined by more uniform cuboidal
cells with eosinophilic cytoplasm and bland cytologic features when compared with serous carcinoma, but this is not true when mesothelioma of the tunica vaginalis testis is poorly differentiated.
The epithelial lining of the drainage system varies from nonkeratinizing squamous epithelium (canaliculi) to cuboidal
and columnar epithelium containing interspersed mucus-secreting goblet cells (sac and duct).
However, the presence of cuboidal
or columnar cells containing pale and ovoid nuclei with eosinophilic cytoplasm is in contrast with the hyperchromatic and angulated cells of ACC.
The tubular structures were lined by a single layer of flattened to cuboidal
to hobnail-like cells.
For this study, primordial follicles were defined as those containing single layer of flattened granulosa cells surrounding the oocyte (30-50 [micro]m), primary follicles as those with single layer of cuboidal
granulosa cells (50-90 [micro]m), and secondary follicles as those with two or more layers of cuboidal
granulosa cells and no antrum (100-150 [micro]m).
Glandular lobules comprised mostly cuboidal
cells with large pleomorphic nuclei.
Other signs of dry rot are usually grey strands that become brittle and cuboidal
cracking along and across the grain of the wood.
MK-DIECs are cuboidal
(characteristic of epithelial cells), express epithelial marker (pan-cytokeratin), and show extensive proliferation in culture.
To put a figure on the cycle time reduction gained by cooling outside the mold, Bayer MaterialScience AG, Leverkusen, Germany, performed thermal simulations for a 20-mm-thick cuboidal
part of polycarbonate (Fig.
