Keratinocyte differentiation requires intricately coordinated spatiotemporal expression changes that specify epidermis structure and function. For almost 30 years, keratinocyte differentiation has been studied in numerous cell models including keratinocyte primary culture with various supplemented culture media. Structure, function, and differentiation of the keratinocyte. Keratinocytes originate in the stratum basale and migrate to the stratum corneum, the outermost barrier layer of the skin. Strain XB, an established keratinocyte line of mouse teratomal origin, also forms cornified envelopes, but the kinetics of the process are different, indicating that the program of terminal differentiation is not initiated at corresponding times in the two cell types. Some of the transit amplifying cells continue to proliferate then commit to differentiate and migrate towards the surface of the epidermis. Our Primary Human Keratinocyte Cell Cultures are optimized to synthesize keratinocyte cells, the predominant cell type in the epidermis. During this process, they profoundly change their morphology and start to produce keratin, cytokines, growth factors, interleukins and complement factors.  |  Rheinwald JG (1989) Human epidermal keratinocyte cell culture and xenograft systems: applications in the detection of potential chemical carcinogens and the study of epidermal transformation.
