Figure 4

The tumor control of NK cells by neutrophils in vivo. The tumor was subcutaneously injected under the axilla at the same time as the BMT. PBS, PB, and G-PB were intraperitoneally injected on days 7, 14, and 21 after BMT to enhance the activity of NK cells. Tumor size measured using calipers and acute GVHD scores were checked on days 7, 14, 21, and 28. PBS: ; PB: ; G-PB: . .
