Detailed explanation-1: -Keratinocytes produce keratin, a tough, protective protein that makes up the majority of the structure of the skin, hair, and nails. The squamous cell layer is the thickest layer of the epidermis, and is involved in the transfer of certain substances in and out of the body.
Detailed explanation-2: -Keratinocytes proliferate in the basal layer of the epidermis and start differentiating on their way to the surface, undergoing gradual differentiation. During this process, they profoundly change their morphology and start to produce keratin, cytokines, growth factors, interleukins and complement factors.
Detailed explanation-3: –1-the keratinocytes: compose most of the epidermis. They produce a protein: the keratin that helps waterproof the skin and that protects the skin and the underlying tissues from heat, microbes, abrasion and chemicals.
