Tracheal cell function
Splet09. jul. 2013 · Drosophila tracheal terminal cells have become a powerful genetic model to identify and elucidate the roles of genes required for generating cellular morphologies. Terminal cells are a component of a branched tubular network, the tracheal system that functions to supply oxygen to internal tissues. SpletPrecise control of epithelial tube size is critical for organ function, yet the molecular mechanisms remain poorly understood. ... Ice.

SpletPrimary Human Tracheal Epithelial Cells (HTEpC) are isolated from the surface epithelium of human trachea and stain positive for cytokeratin. The respiratory epithelia are responsible for the lubrication of the lungs, the maintenance of humidity, and the cleaning of the respiratory tract.
SpletTo identify other genes important to the development or function of ciliated cells, differential display was used to compare mRNA isolated from cultures of ciliated or nonciliated rat tracheal epithelial cells. Two novel genes, KPL1 and KPL2, have been identified whose expression is increased in parallel with ciliated-cell differentiation.

SpletBronchial/Tracheal cells are responsible for producing lubricating mucus to keep the airways functional and they are a type of epithelial cell, a term used generally to refer to cells lining the inside or outside of the body. These cells generate mucus and a number of other compounds, which play an important role in respiration.
SpletGoblet cells are simple columnar epithelial cells that secrete gel-forming mucins, like mucin 5AC. The goblet cells mainly use the merocrine method of secretion, secreting vesicles into a duct, but may use apocrine methods, budding off their secretions, when under stress. The term goblet refers to the cell's goblet-like shape.
