keratinizálatlanok

Keratinizálatlanok is a Hungarian term referring to cells that have not undergone keratinization. Keratinization, also known as cornification, is a process where cells accumulate keratin, a tough, fibrous protein, and eventually die, forming a protective layer. This process is characteristic of the epidermis of the skin and other stratified squamous epithelia. Cells that have not keratinized, or are in earlier stages of differentiation before significant keratin accumulation, are considered keratinizálatlanok.

These cells typically reside in the deeper layers of the epidermis, such as the stratum basale and stratum spinosum. They are metabolically active, capable of cell division, and are responsible for producing new cells that will eventually migrate towards the surface and undergo keratinization. In contrast, the outermost layer of the skin, the stratum corneum, is composed entirely of dead, fully keratinized cells. The presence and state of keratinizálatlanok are crucial for skin health, wound healing, and maintaining the barrier function of the skin.
