Three cell types--gland cells, columnar epithelial cells
, and multiciliated cells--were observed in the infundibular epithelium.
The mucosa is lined by simple columnar epithelial cells
with microvillous border and occasional mucus cells.
Bar: 200[micro]m; B: Columnar epithelial cells
(Ep) with basophil cytoplasm (*) and nucleus with predominate decondensed chromatin.
Pseudostratified columnar epithelial cells
were absent from some areas.
The mucosa of intestine is made up of simple, long absorptive columnar epithelial cells
each with basally and centrally placed nucleus.
The neoplastic cells were single to double layered, cuboidal to low columnar epithelial cells
and abundant eosinophilic cytoplasm and lumen contained copper coloured secretions.
The first component is that of cystic or multicystic spaces lined by cuboidal to columnar epithelial cells
with clear cytoplasm, or flattened epithelial cells containing eosinophilic cytoplasm with nuclei protruding into the cyst lumen in a hobnail fashion (Figures 1 and 2).
The VP has moderate to large acini comprised of cuboidal to simple columnar epithelial cells
, which have basally located nuclei containing small nucleoli.
Cytology of cast-off cells from the rectum revealed normal subleaf nuclear granulocytes, lymphocytes, histiocytes, columnar epithelial cells
, and squamous epithelial cells.
In the gastrointestinal portion of the alimentary tract, tight junctions between the simple columnar epithelial cells
of the mucosa serve as a selectively permeable barrier.
