||Abstract: "A new approach to determine the transit time through the epidermis is presented, involving a gentle washing of the skin surface to collect the loosely attached surface corneocytes. This, it is believed, will be less likely to stimulate the system than tape-stripping or scraping. Radioactively labelled thymidine and iododeoxyuridine have been used to label cells in the basal layer and various labelled amino acids (glycine, cystine and methionine) have been used to label the metabolically viable cell layers (up to and including the granular layer)."
||Abstract: "The granular to surface time in mice is about 5 days." P.469 figure 5: Range for mouse is 4-6 days. Range for human is 21-28 days
