Figure 2: Results of relative proliferation (BrdU incorporation, representative with ) and intracellular (MTT-reduction) and extracellular enzyme activity (WST-1 reduction) of NHDF treated with 10 μg/mL St. John’s Wort polysaccharides for 48 h. As positive control, 10% FCS was used. Values were normalized to untreated cells (—: untreated control = 100%). . Error bars = SE; * compared to untreated cells and o: to Hp4.
