Representative scans from the four groups and the control peptide. Images from each of the four groups of mice injected with 99mTc cyclo-RGD and imaged on days 3 to 7 after left femoral artery ligation with mean values for ratios for L/R hindlimb below each image. Image in the right shows a representative scan from an animal injected with control peptide. The yellow arrows point to the tracer uptake. The color table shows the highest counts in red through purple to blue and green is background. The bladder is labeled.
