Comparison of cytokine secretion into culture supernatants between original MT-2 cells and subline CB-1, which was continuously exposed to chrysotile for more than eight months. Cytokines were measured using the cytometric bead array of the human Th1/Th2 cytokine kit II, and measurements were made using FACSCalibur flow-cytometry according to the manufacturer’s instructions. Statistical analysis was performed using StatFlex version 5.0 software (Artech) and StatView-J 5.0 software (SAS Institute)
