Figure 2: Three histograms of expression on each cell markers of CD80 and HLA-DR for each of the MDDC Sample 10 and MDDC Sample 11 were displayed as exemplars. Histogram in red line showed the cell marker profile of MDDCs without SFI treatment. These saline controls served as the baseline for the comparison with two other histograms: blue (SFI diluted 1 in 20) and green (SFI diluted 1 in 40) accordingly.
