ITGAM and melanoma: Regarding the myeloid populations (macrophages and neutrophils) that were recruited to the tumors, we found that B16F10 melanoma recruited more macrophages (F4/80+ cells) than TC-1 tumors; macrophages corresponded to 42 ± 3% of the CD45+CD11b+ population whereas in TC-1 tumors, macrophages corresponded to 28.7 ± 2.6% of this population (Figure 4).
