Question

Difference between keratinocytes and non keratinocytes

Answer 1

It is known that 95% of the cells in the epidermis are keratinocytes. ... Keratinocytes are maintained at various stages of differentiation in the epidermis and are responsible for forming tight junctions with the nerves of the skin. They also keep Langerhans cells of the epidermis and lymphocytes of the dermis in place.
whereas.,
Three cells essential for the function of the mature epidermis are not keratinocytes. Two of them are derived from extracutaneous sources and migrate from their tissue of origin into the epidermis. The third probably derives from the keratinocyte but is so extensively modified by differentiation that it bears no resemblance.
