Adult Epidermal Keratinocytes (AEK)

Adult epidermal keratinocytes are the most common type ofAdult epidermal keratinocytes are cells foundAdult epidermal keratinocytes are the main type of cells found in the outermost layer of the skin, known as the epidermis. These cells play a crucial role in maintaining the barrier function of the skin and protecting the body from environmental stresses, such as UV radiation, pathogens, and chemicals.

Adult epidermal keratinocytes are responsible for producing the tough, fibrous protein called keratin, which helps to strengthen and waterproof the skin. They also play a role in the regeneration and repair of the skin following injuries or damage.

These cells undergo a process called keratinization, in which they move up through the layers of the epidermis, gradually losing their nuclei and other organelles as they differentiate into mature keratinocytes. Eventually, these keratinocytes form the outermost layer of the skin, known as the stratum corneum, which provides a protective barrier against external threats.
