Keratinocytes are the most important of the epidermal cells because? they produce a fibrous protein that gives the skin its protective  properties.n epidermal cell is a cell that is part of the outer layer of an organism. For example, in humans, skin cells are epidermal. Leaves on plants have epidermal layers on the to â¦ p and bottom of the leaf.
The keratinocytes divide in the skin's mitotic layer. The innermost part of the epidermis, this is made up of a single line of keratinocytes held together and to the underlying dermis by desmosomes, a sort of press stud structure. Each keratinocyte divides to produce two identical daughter cells.erkel cells (6-10% of the cells in the epidermis), situated between the keratinocytes in the renewal layer, remain in contact with a nerve ending. They can be isolated or grouped together in clusters called Merkel corpuscles.
