The concept that mammalian epidermis is structurally organized into functional epidermal units has been proposed on the basis of stratum corneum (SC) architecture, proliferation kinetics, melanocyte:keratinocyte ratios (1:36), and, more recently, Langerhans cell: epidermal cell ratios (1:53). This article examines the concept of functional epidermal units(More)
A novel mathematical and molecular hypothesis is proposed to account for the peculiar organization of human epidermis. Mathematically, the organization of the interfollicular epidermis is hypothesized to be a tetratomic identity manifesting a gravitational logic in the arrangement of its functional compartments. The squares of the natural numbers; i.e., 1,(More)
