Fig. 5. Histologic appearance of mouse hind paw tissue. A displays a micrograph of nonincised hind paw skin from the plantar surface after hematoxylin and eosin staining. A normal stratified epithelial architecture was observed. B is a micrograph of tissue directly adjacent to an incision. This tissue was harvested 24 h after the incision was made. The section is remarkable for the massive predominantly neutrophilic infiltration of leukocytes and scattered erythrocytes. Both images were obtained using a 40× objective.
