Since they are made up of these materials, epithelial tissues line areas … WebThe widest basal cells occurred at the wound edge and close to the tip of the migrating epithelial sheet; thus they were found in regions where the rate of mitotic division was greatest. The width of the hypertrophic basal cells was 210 to 240 per cent greater than that of the normal basal cell.
