Keratinocyte

These cells, which make up the largest group in the epidermis and the hair follicle, are responsible for the synthesis of keratin that takes place in either the stratum corneum or the hair shaft.
Keratinocytes originate in the basal layer of the epidermis, where they multiply by dividing. As they migrate outward towards the skin’s surface they produce lipids, NMF and keratin. During this process, keratinocytes become progressively flatter, lose their nuclei and die. They are then referred to as corneocytes.
