Figure 3: Effect of BPP on PPAR. agonist-induced adipocyte differentiation Confluent 3T3-L1 pre-adipocytes were differentiated into adipocytes with BPP(5, 10, 25, 50, and 100 μM) in the presence of troglitazone (10 μM) for 8 days. On day 8, the lipid contents of cells stained with Oil Red O were quantified. Results represent the mean ± SD of three independent experiments, each performed in triplicate wells. ### p < 0.001 versus untreated control; * p < 0.05, ** p < 0.01, ***p < 0.001 versus differentiated cells.
