||"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)."
||"The empirical measurements listed in Table I can be used to
estimate proportionate relations between cell compartments in
normal skin. These measurements represent best estimates culled
from the skin biology literature and are therefore mean values
standing in for the remarkable heterogeneity of human skin. Despite
the empirical origin of these measures, certain mathematical
coherences can be discerned."
