Photomicrograph showing a late stage in the epidermal repair of a skin wound. The initial injury was caused by an incision through the full thickness of the skin and partially into the hypodermis, which contains adipose ceils (A). The epidermis has re-formed beneath the scab. The asterisk marks an artifact where epithelium separated during specimen preparation. The scab, which contains numerous dead neutrophils in its inferior aspect, is close to the point of release. The dermis at this stage shows little change during the repair process but will ultimately reestablish itself to form a continuous layer. xllO.
