Goblet cells a level biology
WebGoblet 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. The apical portion is shaped like a … WebOct 30, 2024 · As previously suggested 33, the expression of goblet cell factors is not evenly distributed, indicating the existence of different goblet cell subsets. For example, strong Tff3 staining was mostly localized on goblet cells closer to the crypt tips, suggesting that its synthesis and accumulation occurred in the more mature subset of cells.
