- Abstract
Morphologic and quantitative observations were made of the dendritic cell population of the oral epithelium of Rhesus monkeys. Basal and suprabasal cells were identified with the light microscope using the dopa and osmium iodide reactions. A comparison of pigmented and unpigmented tissues revealed a quantitative difference in the distribution of the basal dendritic cells. Suprabasal cells did not vary with the degree of pigmentation. The number of suprabasal dendritic cells was higher in keratinized tissues. The keratinized dorsum of the tongue contained the largest number of suprabasal dendritic cells. Electron microscopic examination indicated the presence of three dendritic cell types: melanocytes, Langerhans cells, and non-specific dendritic cells. Melanocytes were seen in pigmented and unpigmented tissues. Langerhans cells were observed only in keratinized epithelia. Non-specific dendritic cells were divided into two categories: "low level dendritic cells" (basal) and "high level dendritic cells" (suprabasal). These cells, possibly related to melanocytes and Langerhans cells, were seen in all tissues examined.
