Goblet Cells

   Also found in: Dictionary/thesaurus, Medical, Wikipedia 0.01 sec.
Goblet Cells 

glandular epithelial cells in vertebrate animals and man that secrete mucus. Goblet cells are distributed individually in the mucous membranes of the intestine, air passages, efferent ducts of the pancreas and parotid glands, and the conjunctiva of the eyes. Goblet cells are formed from ordinary epithelial cells. The upper part of goblet cells, which is covered with microvilli, accumulates granules of secretion (mucinogen) that turn into a mass of mucus (mucin) when they absorb water. Goblet cells acquire the shape of a goblet (hence the name) when their apex swells and their base narrows. The upper part of the cells is then destroyed (apocrine secretion) and mucus is released into the lumen of the organ. The walls of the goblet cells collapse, become prismatic, and begin again to accumulate secretion.

The dryness results in part from a loss of goblet cells, which reappear after vitamin A deficiency is corrected.
Although it seems logical that an increase in the density of goblet cells is related to an increase in the risk of neoplastic progression, this hypothesis has never been tested objectively.
The induration of the tracts that the patient had experienced during the upper respiratory tract infection might have been caused by the reactive hyperplasia of lymphoid tissue within or adjacent to the tracts or by an increase in mucosal secretion from the goblet cells of the lining epithelium.
