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.
朗格汉斯细胞存在于主胰管上皮衬里的规则柱状细胞之间。这些细胞形成树突状细胞质突起。透明的细胞质、凹陷的细胞核、无桥粒以及存在特定的伯贝克颗粒是这些细胞的进一步特征。朗格汉斯细胞出现在单层柱状上皮中，这与在角质化过程中所提出的功能相悖。
