epidermal cell proliferation was followed from 18 to 54 h ( 0.005 % cream ) or from 18 to 30 h ( 0.02 % cream ) after the treatment by estimating the rate of g2-m cell flux ( the mitotic rate ) by means of colcemid , and epidermal dna synthesis by counting labeled cells after pulse-labeling with 3h-thymidine .
