Effect of substances on fibroblasts migration. Migration of NIH 3T3 cells (30000/filter) by 0712-1(succussed solvent), 0712–2 (remedy) and 0712–3 (unsuccussed solvent) after 24 h was measured by chemotaxis using 10% FCS as chemoatractant and are expressed as percentages normalized to the untreated control value. As positive control 2 ng/ml EGF was used. Means ± SD from three independent experiments performed in duplicates are presented. All values with different letters are statistically different (p < 0.05).
