Figure 9. FITC-dextran uptaking experiments were performed. The treated BMDCs were suspended in RPMI 1640, incubated with 1 mg/ml of FITC-dextran for 1h at 37°C or 4°C, and then used in uptake experiments. The quantitative uptake of FITC-dextran by the BMDCs was determined by the FACS analysis. Each data point represent the mean ± SEM (n = 3)(*p < 0.05, **p < 0.01).
