Figure 3. Effects of EGCG on cell metabolic activity in HCEpiC. Cells were cultured in complete (HCGS-containing) medium, followed by glucocorticoid-free medium for 18 h. Cells were then treated with IL-1β (A) or 440 mOsm hyperosmotic basal media (B) in the presence of EGCG for 18 or 24 h, respectively. Cell metabolic activity was determined using an alamarBlue assay. Data are presented as mean±SEM, n=3. *versus IL-1β for panel A and 440 mOsm media for panel B; p<0.05.
