Figure 2: BrdU incorporation as marker for cell proliferation. NHEK (a), HaCaT (b), and NHDF (c) were incubated with TSw and TSc in concentrations of 0.01–100 µg/mL for 48 h. Mean values ± SD of replicates of three independent experiments are shown with and compared to untreated cells as well as with compared to cells treated with 0.01 µg/mL and 10 µg/mL TSc; 10% FCS = positive control. Results were normalized to untreated cells (=100%, black line).
