ITGAM and neoplasm: An increased number of neutrophils (SSChigh CD11b+ SiglecF- GR-1+), monocytes (CD45+ CD11b+ SiglecF- Ly6Chigh), and macrophages (CD11b+ CD64+ F4/80+ SiglecF-) were observed in the lung at day 28 post-tumor-cell inoculation relative to the tumor-free controls (Figure 1a–c) This time point correlates with the appearance of micrometastatic lesions in the lungs.
