Keratinocyte: Epidermal skin cell that makes Keratin and eventually undergoes differentiation to become a dead, flattened cell of the stratum corneum.
Keratitis: Inflammation of the cornea of the eye.
The main kind of cells that make up the epidermis are keratinocytes, melanocytes, Langerhans cells and Merkels cells. The epidermis have 5 layers Stratum basale ,stratum spinosum ,stratum granulosum, stratum licidum and stratum corneum.
Retinoids decrease the cohesiveness of abnormal hyper-proliferative keratinocytes and may reduce the potential for malignant degeneration and consequently reduce the risk of skin cancer in patients who have undergone renal transplantation.
The epidermis also hosts different types of cells: keratinocytes, melanocytes and Langerhans cells. Keratinocytes produce the protein known as keratin, the main component of the epidermis. Melanocytes produce your skin pigment, known as melanin.
The Melanin that the melanocytes make finds its way into the keratinocytes (the cells containing the keratin) as they make their way up to the surface. The melanocytes produce more melanin when we are exposed to the sun. The result of this is a tan.
The type and amount of melanin synthesized by the melanocyte and its distribution pattern in the surrounding keratinocytes determines the actual color of the skin.
