Figure 3From: Spontaneous regression of metastatic cancer cells in the lymph node: a case reportComparison of Foxp3 and CD56 cell distribution. (A-C) Foxp3 staining. (D-F) CD56 staining. Higher density of Foxp3(+) Treg cells in the metastatic lymph nodes and more infiltration of CD56(+) NK cells in the tumor regressed lymph nodes were observed (Inserts showed higher magnification views).Back to article page
