Figure 1. SkQ1 accelerates wound closure in old mice. Full-thickness 7×7 mm excisions were made on the interscapular area of the back skin of young (6 month, n=12), old (24 month, n=12) and old mice received SkQ1 (100 nmol/kg of body weight per day) during the last 8 month of life (n=10). (a) Representative photos of wounds, (b) dynamics of wound closure. Data are presented as mean ± SD; *P < 0.05 for SkQ1-treated versus old mice.
