Keratinocytes
The most abundant epidermal cells, they function mainly to produce keratin.
Keratinocytes are the most abundant cells found in the epidermis or outer layer of the skin. They account for about 90% of the cells found in the epidermis, and their primary function is to produce and maintain the protective barrier of the skin. Keratinocytes produce a tough, fibrous protein called keratin, which makes up the majority of the skin’s outer layer.
These cells serve numerous functions, including the protection from environmental factors, the prevention of water loss through the skin, and the production of vitamin D. They also play a vital role in the healing process of wounds and injuries to the skin. Keratinocytes undergo a process called keratinization, which involves the production of keratin and the hardening and flattening of the cells as they move towards the skin surface, forming a protective layer.
In summary, keratinocytes are an essential component of the skin’s protective barrier and play a crucial role in maintaining skin health and function.
