Abstract:
By means of ATPase histochemistry and OKT-6 immunogold-silver staining, it was demonstrated that Langerhans ceils (LC) were present in the epithelia of human skin, palatine tonsil, ectocervix and esophagus. In the skin LC were located mainly in the stratum spinosum of the epidermis. There were some LC in the hair follicle and duct of sebaceous gland, and a few in the dermis and around sebaceous gland acinus. In the tonsil, ectocervix and esophagus, LC were located mainly in the middle layer of epithelia. No LC were found in the lymphoid follicle and thymus-dependent zone of the tonsil, and no LC in the lamina propria of ectocervix and esophagus. ATPase histochemistry was also used to examine the distribution of epidermal LC in normal human skin of various ages and various anatomic regions. This study showed that the density and morphology of epidermal LC varied with age and different anatomic regions of human body. Statistical analysis indicated that LC density in various age groups was as follows: fetus
