Detailed explanation-1: -Goblet cells arise from pluripotent stem cells and derive their name from their goblet, cup-like appearance. The primary function of goblet cells is to secrete mucin and create a protective mucus layer.
Detailed explanation-2: -The mucins produced by the goblet cells are the classical gel-forming mucins MUC2, MUC5AC, MUC6 and MUC5B which are secreted by the intestine, stomach surface, stomach glands and salivary glands, respectively. All of these form extremely large polymers. The enterocytes also express mucins, but of another type.
Detailed explanation-3: -Goblet cells are a specialized type of epithelial cell that secrete mucins (any of the class of glycoproteins found in mucus e.g. saliva, gastric juice, secreted by mucous membranes) which are significant components of mucus.
