different methods were employed in order to determine epidermal proliferation parameters such as : a. the cytophotometrically measured amount of nucleic deoxyribonucleic acid ( dna ) of feulgen-stained epidermal basal cells , b. the total dna content of whole epidermis , c. the number of colcemid ( r ) arrested metaphases ( mitotic rate ) in the basal cell layer , d. the incorporation of h3-thymidine into dna of epidermal basal cells .
