Fig 7. In vitro scratch assay of dermal fibroblasts and supernatants from IAT and HAT.

Fig 7

Wound healing of human dermal fibroblast monolayers was evaluated by an in vitro scratch assay. Fibroblasts were incubated with supernatants of samples from IAT and HAT, MIF-dependency was evaluated by anti-MIF antibodies. Medium containing 10% FCS served as a PC and medium containing 0% FCS served as a NC. Experiments were performed in the presence (A, B) and absence (C, D) of the proliferation inhibitor Mitomycin C. A Supernatants from IAT show a decreased induction of fibroblast proliferation and migration (no Mitomycin C). B Fibroblast proliferation and migration is increased by addition of MIF-antibodies (no Mitomycin C). C Supernatants from IAT show a decreased induction of fibroblast migration (10 μg/ml Mitomycin C). D Fibroblast migration is increased by addition of MIF-antibodies (10 μg/ml Mitomycin C). All measurements were normalized to the negative control of Fig 7A which was set as 1. Data are presented in relative migration distance of fibroblasts ± SEM. Statistically significant differences are indicated by asterisks (*, p<0.05; **, p<0.01; ***, p<0.001).
