Primary Epidermal Keratinocytes; Normal, Human, Neonatal Foreskin (HEKn) are cells isolated from the skin of a normal male. Normal Human Primary Epidermal Keratinocytes from Neonatal Foreskin provide an ideal cell system to propagate keratinocytes in serum-free (not animal-free) conditions when grown in Dermal Cell Basal Media supplemented with Keratinocyte Growth Kit components. The cells are cryopreserved in the first passage to ensure the highest viability and plating efficiency. ATCC Primary Cell Solutions cells, media, supplements and reagents are quality tested together to guarantee optimum performance and reliability. Use this cell line in your research in toxicology, wound repair, skin cancer, response to UV radiation, psoriasis, eczema, viral infection, gene delivery system, and cellular differentiation.
