Effect of puerarin on oxLDL-induced foam cell formation in human THP1 macrophages. The THP1 macrophages were treated with oxLDL (50 μg/mL) with or without puerarin at various doses (from 10 μg/mL to 100 μg/mL) for 72 hours. Oil red staining was performed, and oil red staining intensity was measured for the quantitation of the lipid accumulation in the foam cells. (a): representative images; (b): oil red intensity was quantified. ^∗ P < 0.05 versus oxLDL. n = 5.
