Name the cells that produce keratin in the skin?
A keratinocyte is the predominant cell type in the epidermis, the outermost layer of the skin, constituting 90% of the cells found there. Those keratinocytes found in the basal layer (stratum basale) of the skin are sometimes referred to as "basal cells" or "basal keratinocytes.
Which skin layer acts as a shield?

What are most cells of the epidermis?

What layer of the epidermis is the layer where mitosis occurs?
We find it in the deepest layer of the epidermis called Stratum Basal in which the stem cells undergo Mitosis replacing keratinocytes lost at the stratum corneum, the apical surface of epidermis.
What type of cell division happens to skin?
Mitotic cell division occurs in the Basale layer of the epidermis. Stem cells undergo mitosis to produce new keratinocytes. Of the two keratinocyte daughter cells produced by mitosis, one migrates to the surface of your skin while the one remains in the basale layer of the epidermis to produce more keratinocytes cells.
In which layer of the epidermis are lamellar bodies formed inside keratinocytes?
stratum lucidum
What is the substance in the cell of the epidermis that toughens the skin and makes it waterproof?
Keratinocytes
Is hemoglobin found predominantly in the stratum corneum?
