ITGAM and neoplasm: To validate the infiltration of neutrophils, we applied flow cytometry analysis to identify CD11b+ Ly‐6G+ cells, commonly recognized as tumor‐associated neutrophils (TANs).[33, 34] We observed a significant increase in CD11b+ Ly‐6G+ neutrophils in tumor‐bearing lungs from the recipient mice intravenously injected with either clone of shNKX2‐1/LL2 cells, compared to control mice transplanted with shCtrl/LL2 cells or the healthy lungs (Figure 3H,I).
