The epitrichium covers the floor of the embryo and undergoes a ongoing cycle of keratinization (replacing the cell cytoplasm with keratin) and desquamation (shedding with the outer layer of tissue) for 21 weeks. The basal layer (stratum germinativum) acts as being the germinal layer that continuously replicates to switch superficial cells shed for the duration of desquamation.
