Langerhans cells in the epithelium of main pancreatic ducts.
Langerhans cells are present among regular columnar cells in the epithelial lining of main pancreatic ducts. The cells form dendritic cytoplasmic processes. Clear cytoplasm, indented nucleus, absence of desmosomes, and presence of specific Birbeck granules are further characteristic features of these cells. The occurrence of Langerhans cells in a simple columnar epithelium argues against a proposed function in the process of keratinization.
