Figure 6. Effect of basic fibroblast growth factor (bFGF) on the regulation of cellular ATP levels in normal and hypertrophic scar (HS) fibroblasts. Cells were grown and treated with bFGF at concentrations of 0.1 to 1000 ng/mL for 72 h and then subjected to the luciferin-luciferase assay. bFGF decreased the intracellular ATP levels in HS fibroblasts and increased the ATP levels in the normal fibroblasts. Data are reported as means ± SEM. *P < 0.05, **P < 0.01 vs untreated fibroblasts (paired t-test and one-way randomized ANOVA).
