Haematoxylin and Eosin (H&E) staining of skin at different time points during the gel-based treatment (a). Stained images (100x magnification) were shown for all four groups (AM, AV, AM+AV, and non-treated control) at day 6 (a1-a4), 12 (a5-a8), 18 (a9-a12), 24 (a13-a16) and 30 (a17-a20). Re-epithelialization (b), inflammatory (c), and angiogenesis (d) scoring from the images represents a qualitative and quantitative assessment of healing. Black double headed arrow represents the thickness of epidermis; single headed blue arrow shows the keratinized zone of skin, single headed black arrow projects the blood vessel, formation of new glands beneath the epidermis is shown in blue box (a17, a18), and inside the blue round box (a19) some basal keratinocytes were shown
