Fig. 7. Immunodetection of Egr1 in wounds. Cryosections of 13-day-old wounds from wild-type animals were stained with an antibody against Egr1. Keratinocytes in the newly formed epithelium at the wound margin exhibit strong induction of Egr1 (A), whereas distal to the wound margin, hardly any upregulation is seen (B). Arrowheads indicates the epidermal/dermal junction. Bars, 50 µm.
