Human TESS are models of epidermal differentiation expressing various epidermal markers. Normal human skin and TESS present the four expected epidermal layers: the basal, spinous, granular, and cornified layers. Enzyme eLOX3 is similarly expressed in TESS when compared with normal human skin 748344
