Cells in the dominant subcluster (Neu_0, Neu_1, Neu_2, and Neu_5) with high expression of Ccl3 and Cstb defined as tumor‐specific neutrophils,[19] which were enriched in the NPs group and exert pro‐tumor effects with a similar expression pattern of Cd274, Vegfa, and Lgals3 (Figure 5l,m). The gene discussed is CD274; the disease is neoplasm.
