郎格罕氏细胞(Langerhans cell)是一种胞浆带有突起的细胞,可见于多种部位的鳞状上皮内。由于郎格罕氏细胞可参与表皮角化并属于单核巨噬系统,故其重要性已为越来越多的人们所重视。Al Yassin和Toner首先在电子显微镜下观察到人类食管上皮内郎格罕氏细胞的存在。以后,有人用ATP酶法以及免疫组织化学方法观察和证实食管上皮内郎格 Langerhans cell is a cytoplasm with protruding cells that can be found in various parts of the squamous epithelium. Because of the role of Langerhans cells in epidermal keratosis and belongs to the mononuclear macrophage system, the importance of Langerhans cells has been paid more attention to by more and more people. Al Yassin and Toner first observed the presence of human esophageal epithelial cells within the electron microscope. Later, some people with ATP enzymatic and immunohistochemical methods to observe and confirm esophageal epithelial Lang Lang
