OxLDL-induced lipid accumulation and cell viability changes in human THP 1-derived macrophages. THP-1 macrophages were incubated with 80 ug/mL oxLDL for 0, 6, 24, 48, and 72 h. The intracellular lipid accumulation was determined by oil red staining and quantified with IPP software (a); (b) During the courses of foam cells formation and progress, cell viability was measured with MTT staining; (c) The data are expressed as means ± SD from at least 3 independent experiments. *P < 0.05 vs. 0 h. scale bars = 25 um
