Figure 3.
Ni-NPG staining of DCs from various LNs. (a) Cells were incubated with 100 μM NiCl2 for 60 min followed by NPG. Histograms represent the NPG fluorescence of cells incubated with (black line) or without (gray-shaded) NiCl2. Results are representative of three independent experiments. (b and c) Ni-NPG staining of migratory (b) and resident (c) DCs was analyzed. Results are shown as ΔMFI. Bars represent the mean ± SD of three independent experiments. Each symbol represents the value from an independent experiment. Means without a common letter were significantly different, P < 0.05.
