Abstract
The available data suggest that epidermis is organized as a system of discrete structural–functional units (SFUs) that reproduce both in vivo and in vitro. SFUs are formed in the culture of epidermal keratinocytes via self-organization of the developing cellular elements. SFUs are capable of self-maintenance and form a niche for stem cells. At the same time, due to the maintenance of asymmetric proliferation kinetics of the stem cells, SFUs serve as a barrier to their uncontrolled replication.
