The presence and localization of onychodermis (specialized nail mesenchyme) containing onychofibroblasts in the nail unit: a morphological and immunohistochemical study

Abstract

These results demonstrate the presence and localization of a specialized nail mesenchyme containing onychofibroblasts in a well-defined area beneath the nail matrix and nail bed. Thus, we propose the term onychodermis for this specialized nail mesenchyme that is histologically and immunohistochemically distinct from the dermis of other parts of the nail unit.
