Which cells of intestinal mucosal epithelium secrete mucus?

Goblet cells are specialised mucus-secreting cells of the intestinal mucosal epithelium. They are modified columnar epithelial cells that release mucus, which lubricates the gut lining and protects it from friction and digestive action. Chief cells (peptic cells) of the stomach secrete pepsinogen, and oxyntic (parietal) cells of the stomach secrete hydrochloric acid and intrinsic factor, so none of these gastric cells are responsible for mucus secretion in the intestine.
