TNF-α concentrations in the supernatant of macrophage cell culture after incubation with different concentrations of cystine crystals (experiment 1). A triplicate of each concentration was performed in two separate experiments. Concentrations were expressed as pg/μg protein of macrophage pellets. Horizontal bars represent the range of TNF-α values for each crystal concentration.
