Fig. 2.

Microscopic images of skin tissue samples of 14th day with magnification of × 400.

C+: PMNs population decrease and epithelium regeneration is observable in wound edge but not in wound center (neovascularization: +).

C-: high density of blood vessels and no re-epithelialization, only reduction in PMNs and macrophages (neovascularization: +).

TG5: high density of blood vessels and connective cells, no healing and extreme bleeding in dermis layer (neovascularization: ++++).

TG10: re-generation is almost complete, only stratum keratinosum need to be complete.
