Polysaccharides of St. John’s Wort Herb Stimulate NHDF Proliferation and NEHK Differentiation via Influence on Extracellular Structures and Signal Pathways

Figure 2

Results of relative proliferation (BrdU incorporation, representative with 𝑛=8) 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%). 𝑛=24. Error bars = SE; *𝑃<0.05 compared to untreated cells and o: 𝑃<0.05 to Hp4.
