Epidermal cell models are critical for studying skin biology. The gold standard used by the scientific community has historically been primary cell cultures from discarded tissue, typically from neonates (foreskin). Although directly applicable to humans, this system suffers from multiple issues, including substantial donor-to-donor variability and a finite number of divisions in culture. As such, we have identified a faithful alternative called N/TERT2G cells. These cells show many of the characteristics of primary cells, including barrier formation, differentiation kinetics and/or protein expression, and pathogenesis. From our observations, N/TERT2G cells can serve as a reproducible and genetically manipulatable platform in studying skin biology.
