CD69 and neoplasm: Similar proportions of CD56dim/CD16+ NK cells isolated from the tumor microenvironment of NSG‐Tg(Hu‐IL15) mice express functional markers CD69 (Figure 6K), CD8 (Figure 6L), and NKG2D (Figure 6M), and produce granzyme A (Figure 6N) and granzyme B (Figure 6O) when compared to NSG mice.
