Fig. 7.
Comparison of the relationship between epidermis thickness and wound depth with volume. The grey one indicates thin epidermal engineered skin, and the dark one is thick epidermal skin. (A) The thin epidermal engineered skin has an epidermal layer of 50 μm (from 350 μm to 400 μm), and the initial penetrated hole depth after layer irradiation is about 400 μm. In thick epidermal engineered skin, the epidermal thickness is about 100 μm (from 250 μm to 350 μm) and the initial penetrated hole depth is about 350 μm. The black star indicates the irradiated epidermal area. (B) The initial hole volume after irradiation is 3.3 million μm3 in thin epidermis skin and 1.2 million μm3 in the thick sample.
