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 originate from human epidermal stem cells present in the stratum germinativum (basal layer of epidermis). The progeny of these stem cells are termed transit amplifying (TA) cells. TA cells also reside in the basal layer and undergo mitosis.s the granulosum keratinocytes are pushed into lucidum layer, they become transparent or translucent and get flattened. The lucidum keratinocytes may be 3-5 layers in thickness and may undergo apoptosis releasing fatty substance. They contain a clear intermediate form of keratin called eleidin.
