Effect of different concentrations of recombinant Klotho on cell viability of foam cells. a Foam cells were incubated with various concentrations of recombinant Klotho protein (0 ng/mL, 25 ng/mL, 50 ng/mL, 100 ng/mL, and 200 ng/mL) for 24 h. b Foam cells were incubated with 50 ng/mL recombinant Klotho for different periods of time (0 h, 6 h, 12 h, 24 h, and 48 h)d. ^*P < 0.05 and ^**P < 0.01 vs. control group
