对正常食管上皮作深入的电子显微镜观察将有助于对比食管癌上皮与正常食管上皮的超微结构,发现癌上皮的特征。正常食管上皮的超微结构研究,在鼠、雪貂、豚鼠等动物身上进行的较多。对人则较少。国内的研究多是作为食管癌超微结构研究的一部分内容来进行的。国外,只是近几年来才对人正常食管上皮进行了深入研究。如对朗格罕细胞、胞浆内桥粒、核小体、粘膜下腺体的研究,对细胞连接(桥粒、缝隙连接、细胞侧面复合连接体)
An in-depth electron microscope observation of normal esophageal epithelium will help to compare the ultrastructures of esophageal epithelium with normal esophageal epithelium and to discover the features of the cancerous epithelium. The normal esophageal epithelial ultrastructure research, in rats, ferrets, guinea pigs and other animals carried out more. Fewer people. Domestic research is mostly as part of esophageal ultrastructure research carried out. Abroad, it is only in recent years that human normal esophageal epithelium has been studied in depth. Such as Langerhans cells, intracytoplasmic desmosomes, nucleosomes, submucosal gland research, cell connections (desmosomes, gap junctions, cell side of the complex connector)
