(A) Sections of the excised wounds obtained from either the corn oil or TCDD- treated mice were stained with either Ki67 (left panels) or DAPI (right panels) to identify proliferating keratinocytes within the epidermal layer. Samples obtained at one, two and three days post-wounding were analyzed. Small arrows indicate the apical and basal surfaces of the epidermis whereas the arrowheads indicate the wound edge. (B) The percent of DAPI-stained epidermal nuclei that stained positive for the Ki67 antigen were quantitated. The data are shown as mean ± s.e.m.
