Figure 7From: Destructive impact of t-lymphocytes, NK and mast cells on basal cell layers: implications for tumor invasion Elevated apoptosis in focally disrupted basal cell layers. Paraffin-embedded human prostate tissue sections were subjected to apoptosis assay and also immuostaining for basal cell markers. Note that nearly all apoptotic cells (arrows) are the epithelial capsule element (arrowheads), the basal cells. A and C: 100X. B and D: a higher (300X) magnification of A and C, respectively.Back to article page
