The total cell numbers of KP7 lungs were more than those of KP lungs, which was probably due to larger tumor sizes in KP7 mice than in KP mice (Fig. 3b), whereas the total cell numbers and the percentages of CD11c+, CD11b+CD11c−F4/80+ or CD11b+CD11c−Ly6G+ cells in the bronchoalveolar lavage fluids (BALFs) of KP and KP7 mice were comparable (Supplementary Fig. 4a, b). Here, ITGAX is linked to neoplasm.
