Survival of RAW 264.7 cells during asbestos phagocytosis. Cells were incubated in the absence of asbestos (white bars) or in the presence of 25 μg/mL of either unlabeled (striped bars) or fluorescently labeled (black bars) asbestos for 2 h or 24 h. The data represent the mean of three experiments with at least 100 cells per sample, and the error bars represent the standard deviation. Statistical analysis was performed using the two-tailed unpaired Student’s t-test. NS, not significant
