NK cell levels are correlated between paired serum and tumor samples from patients with GC. (A) Representative immunostaining images of NK cells (CD56) in 20 GC and 3 GU tissues. Blue stains the nucleus, while brown stains CD56 (scale bar, 100 µm). (B) A scatter plot illustrates the correlation of the NK cell levels between paired serum and tumor tissues from patients with GC (Spearman's R=0.898; P<0.001). GU, gastric ulcer; GC, gastric cancer; NK, natural killer.
