Fig. 6. Effect of PLREE on lipid accumulation during the differentiation of 3T3-L1 preadipocytes into adipocytes. 3T3-L1 preadipocytes were treated with PLREE at 100 μg/mL (C), 250 μg/mL (D), and 500 μg/mL (E) for 8 days, and microscopic images of Oil red O-stained 3T3-L1 cells (day 8) were compared to undifferentiated normal cells (A) and differentiated control cells (B). 200× magnification.
