Green tea polyphenol epigallocatechin-3-gallate blocks PDGF-induced proliferation and migration of rat pancreatic stellate cells

Figure 2 EGCG was cytotoxic at higher concentrations. PSCs were treated with EGCG at the indicated concentrations (μmol/L) in serum-free medium for 72 h. Cell viability was determined by the MTT assay, and the absorbance at 570-690 nm (“A”) of the sample is shown. Data are shown as mean±SD (n = 6). ^bP<0.01 vs EGCG at 0 μmol/L. A: optical density.
