Areas subjected to histological evaluation of biopsies (a) or cross sections of wounds (b), hematoxylin and eosin stain. a Histological evaluation of wounds aged 1 h to 10 days was carried out in areas 1–3 (3 mm × 3 mm). Area 1: at the wound edge, dermis. Area 2: at the wound edge, subcutis. Area 3: central in the wound bed. b Histological evaluation of wounds aged 14 to 35 days was carried out in area 4 (3 mm × 3 mm), i.e. central in the granulation tissue. The thickness of the granulation tissue was measured at the center of the wound (straight line)
