MRC1 and melanoma: Although the percentage of CD206+ cells in CD68+ cells had no difference between the 2 groups (as almost all of CD68+ cells in both WT and Colec11–/– mice were positive for CD206), the fluorescence intensity of CD206 in CD68+ cells was lower in the melanomas of Colec11–/– mice than WT controls (Figure 5, A and B).
