Epithelial renewal in skin is achieved by the constant turnover and differentiation of keratinocytes. Three popular hypotheses have been proposed to explain basal keratinocyte regeneration epidermal homeostasis: 1) asymmetric division (stem-transit amplifying cell); 2) populational asymmetry (progenitor cell with stochastic fate); 3) stem cells. In this study, we investigated lineage dynamics using these a 3D agent-based model epidermis. The simulated growth maintenance epidermis over three...
