Chromaffin Reacting Cells in Human Digital Skin

Abstract

These studies demonstrated the existence of chromaffin-reacting granules in the human skin. The chromaffin reaction was provided by bichromate fixation. Subsequent special staining by the modified Sevki procedure revealed these granules to be localized usually to characteristic long, eel-like cells with distinctive tinctorial features. Although the true significance of these cells is not certain, they are believed to represent the local source of a vasopressor material for the peripheral tissues. Much indirect physiologic evidence supports this belief.
