Explanation:
Keratinocytes are in the stratum basale of the epidermis, which is the deepest layer of the epidermis; from this layer, they ascend to the stratum spinosum, then to the stratum granulosum, then to the stratum lucidum if the skin is thick like the one that is in our hands or soles, and lastly they end in the stratum corneum.
