Figure 6From: Destructive impact of t-lymphocytes, NK and mast cells on basal cell layers: implications for tumor invasion Mast and NK cell infiltration within in situ prostate tissues. Paraffin-embedded human prostate tissue sections were triple immunostained with markers for CK34βE12 (red), NK (brown), and Mast (blue) cells. Note again that a majority of NK (thick arrows) and Mast (thin arrows) are located along the tumor capsule (arrowheads).Back to article page
