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

Figure 6 EGCG did not alter the expression of total PDGF β-receptor. PSCs were incubated with EGCG at the indicated concentrations in the absence or presence of PDGF-BB (at 25 μg/L). After 24 h, total cell lysates (approximately 100 μg) were prepared, and the levels of total PDGF β-receptor and GAPDH were determined by Western blotting.
