Fig. 8. Effect of toxin B and ML-7 on wound epithelialization in vitro. Mitomycin-C-treated keratinocytes in FAD low Ca²⁺ were wounded and incubated for 6 hours in the presence of growth factors. Wounded monolayers were stimulated with 100 ng ml^-1 IGF-1 (A,B) or 10 ng ml^-1 EGF (C-E) in the presence of 20 ng ml^-1 toxin B (B) and 5 µM (D) or 10 µM (E) ML-7 or the respective vehicle controls (A,C).
