B: An area of columnar epithelium
was also observed on the inner surface of the cyst.
There is healing of this injured epithelium with specialized columnar epithelium
and intestinal metaplasia (Barrett epithelium).
Cysts were lined by a tall columnar epithelium
, which in some areas was pseudostratified, or by low cuboidal to flattened cells (Fig 10).
Both chlamydia and gonorrhea preferentially attach to the columnar epithelium
, she said.
in both the trachea and bronchiole was intact, thus providing adequate columnar epithelial cells for evaluation.
27 [micro]m to a columnar epithelium
with cell height of 7.
This extension of the single-layered columnar epithelium
onto the ectocervix may facilitate genital tract shedding.
The gill filament is lined by a columnar epithelium
that varies much in thickness in different parts (Figs.
Covering the tentacle is a simple columnar epithelium
lying on a thick basement membrane (Figs.
As this sheet of cells progressed through the dermis, its advancing edges recurved upon themselves and gave rise to an interior adjacent layer of pseudostratified columnar epithelium
Histologically, they are lined with ciliated columnar epithelium
, squamous epithelium, or both.
In one large series of 64 cysts, 41% of cysts showed pseudostratified columnar epithelium
only, and in, respectively, 14% or 23% stratified squamous epithelium or cuboidal epithelium was also present.
Histopathologic examination of the cyst frequently includes stratified columnar epithelium
, whether or not it is associated with mucous cells or glands.
After decades of smoking, cilia gradually disappear and the ciliated stratified columnar epithelium
of the tracheobronchial tree becomes bald.
I recently demonstrated that intestinal lamina propria resident DCs migrate towards and extend cellular processes between the tight junctions of columnar epithelium
through a CCR5-dependent mechanism, take up R5 but not X4 HIV-1, and then transfer infection to susceptible T cells.
