Human Epidermal Keratinocytes (HEK) provide an excellent model to study epithelial function and disease, skin biology, toxicology and HPV infection. When grown on inserts and provided a liquid/air interface, they differentiate into a stratified squamous epithelium, forming a physiological 3D tissue. HEK comprise 90 % of all cells in the epidermis, the outermost skin layer. They produce a barrier, the intermediate filament keratin. Keratinocytes obtain melanin from melanocytes (HEM) and store it as protection from UV radiation. We highly recommend optimized Human EpiVita Media to enhance the performance and in vitro lifespan of HEK.

HEK from Cell Applications, Inc. have been utilized in numerous research publications, for example in basic research to investigate mechanisms of cell senescence and develop ways to extend cell life span. Others have used HEK to design a method to isolate proteins for use in basic researh, and show higher relevance of primary keratinocytes when compared to key differences exhibited by immortalized keratinocyte cell lines. Pharmaceutical companies employ HEK to provide in vitro human skin models that assess effects of cosmetic formulations or anti-inflammatory properties of proposed anti-psoriasis drugs. Translational research on keratinocytes benefits from their ability to model the wound healing response, or help develop serum tests for patients with blistering diseases. HEK are also utilized to understand aggressiveness of cancer phenotypes, investigate compounds for potential topical melanoma treatments, and even develop siRNA therapy targeting oncogenes. In addition, HEK help unravel the oncogenic potential of HPV and test approaches for treating HPV lesions.
