RESPONSES OF THE HUMAN ECCRINE SWEAT DUCT TO CONTROLLED INJURY - GROWTH CENTER OF THE EPIDERMAL SWEAT DUCT UNIT

[摘要] The Epidermal Eccrine Sweat Duct Unit was selectively removed along with the adjacent epidermis by means of a high-speed rotary fine-grained abrasive. Observations of the regeneration of the sweat duct indicate: (a) its growth center to be from a small zone of basal cells where the sweat duct joins the epidermis; (b) these basal cells are indifferent epidermal cells that can become either highly specialized lumenal cells lining the sweat duct or prickle cells; (c) the lumenal cells lining the Epidermal Sweat Duct Unit have the ability to produce spirals and coils in the sweat duct before any epidermis is present.
