Fig 2. CA treatment inhibits apoptotic epithelial and endothelial cell death after IR.
A. Apoptosis in the jejunum at 6 h after 12.5 Gy abdominal IR. Apoptotic FITC-TUNEL (green) and endothelial rhodamine-PECAM1 (red) are shown counterstained with DAPI (blue). Scale bar = 30 μm. B. The distribution of apoptotic cells in crypts and lamina propria and PECAM1 in a villus unit of the jejunum after 12.5 Gy IR. The values represent the mean ± SEM (*p < 0.05, n = 6).
