Peri-incisional infiltration of neutrophils, immunohistochemical appearance. Hind paw skin from incised mice was processed for the identification of neutrophils. Panel A displays an H&E stained section of plantar hind paw skin demonstrating a predominantly dermal cellular infiltrate 2 hours after incision. The dermal and epidermal layers are labeled. Panel B displays the appearance of non-incised hind paw skin stained with a neutrophil-specific antibody. Panel C displays a micrograph taken of incised skin stained for neutrophils 2 hours after incision. Note the abundance of darkly staining infiltrating neutrophils in the dermis of this section compared to that displayed in panel B. The scale bar in panel C is 150 μm in length. All micrographs were taken using 200× magnification.
