Explanation:
Detailed explanation-1: -[10] Thus, keratin is not a cellular secretion, but it is the end result of transformation of ectoderm-derived epithelial cells called keratinocytes into squame of keratin. When these squame are worn away or desquamate from the surface, they are replaced by the process of keratinization.
Detailed explanation-2: -As the stratum basale continues to produce new cells, the keratinocytes of the stratum spinosum are pushed into the stratum granulosum. The cells become flatter, their cell membranes thicken, and they generate large amounts of the proteins keratin and keratohyalin.
