Histological sections of reepithelialization and angiogenesis at day 8 after wounding. Arrows indicate the formation of blood vessel in the wound bed. (a) The newly formed blood vessels and reepithelialization of the wound epidermis in wound location by topical treatment with 5 μg 4 × Tβ4 (dissolved in 50 μL of the 0.9% physiological saline). (b) The newly formed blood vessels and reepithelialization of the wound epidermis in the wound location by topical treatment with 5 μg Tβ4 (dissolved in 50 μL of the 0.9% physiological saline). (c) Treatment with 0.9% physiological saline. (d) Normal mouse skin tissues (bar = 100 μm).
