Figure S1. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining for apoptosis detection. Panel A to C show the representative images of TYNEL staining of rat coronary vessels in myocardial sections. Apoptotic endothelial cells are not identified on Tunnel staining. Panel A: Non-radiated baseline control; Panel B: Radiation; and Panel C: Radiation + Ac-SDKP treated rat. Panel D: Positive control (arrow pointed to show apoptotic myocyte nucleus). N = 8–10, Scale bar: 20 μm, magnification × 400. (DOCX 609 kb)
