AUTOFLUORESCENT GRANULES IN CELLS OF HUMAN DERMIS. II. HISTOCHEMICAL OBSERVATIONS.

Abstract

Cells with autofluorescent granules are common in the dermal connective tissue of human skin. The cytoplasmic granules appear to be of lipo-pigment nature. The cells show phagocytic properties and it can therefore not be excluded that the cytoplasmic granular structures are ingested material. There are certain similarities between the observed dermal autofluorescent cells (DAF-cells) and chromatophores (melanophages) of the dermis. Convincing histochemical evidence has not been obtained for the presence of catecholamines in these fluorescent cells, which has been suggested. (Author)
