Immunofluorescence of the OS-REp models showing the living cells through anti-Ki67 staining. (A) Antigen Ki67 (Ki67) staining the control OS-REp model; scale bar: 50 µm. (B) Merged image of both DAPI and Ki67 staining highlighting the wound edge (dotted line); scale bar: 50 µm. (C) Merged images of day 7 and 14 of the OS-REp models treated with 5% dexpanthenol or without treatment. The images indicate the development of a new epidermal tissue under the old damaged tissue; dotted lines indicate the separation of both tissues; scale bar: 100 µm.
