"Based on these earlier findings we wanted to determine if Bik may be responsible for sustained mucus cell
growth in the airways of cigarette smokers," he said.
To assess the effects of AUB on airway inflammation and mucus cell
content in the airway wall, lungs were excised and fixed in 10% formalin, washed in methanol, dehydrated, embedded in paraffin, and cut into 5-[micro]m sections.
The stomach epithelium comprises 3 cell types: mucus cell
, tall granulated columnar cells with fine granules in the apical cytoplasm, and nongranulated columnar cells.
These are: (1) the cuboidal cells with round nuclei with euchromatin and distinct nucleoli on the lateral side; (2) the tall columnar cells with round or oval nuclei located in the terminal epithelium; (3) the ciliated columnar ceils in the distal end of the filament; (4) the mucus cell
with numerous dense granules packed tightly together in the apical cytoplasm (Fig.
The esophageal mucosa is arranged into longitudinal folds and is composed of simple columnar ciliated epithelial cells interspersed with mucus cells
, especially at the tips of the folds (Fig.
At -196C liquid nitrogen instantly freezes and kills off all the mucus cells
so an exact dose must be administered so other cells aren't damaged.
Fisher (1992) proposed that agglutinating substances could be produced by mucus cells
, or mucocytes.
The lack of anaplasia, mucus cells
, and other cell types typical of mucoepidermoid carcinoma rule out the diagnosis of mucoepidermoid carcinoma.
were present on the surface of sensory epithelium which is surrounded by dense non- sensory cells (Fig.
