Figure 2

Top: Representative images of CM-DiI labeled (red) endothelial progenitor cells (EPC) or mesenchymal stem cells (MSC) in the post-stenotic kidneys of pigs with renal artery stenosis (RAS) 4 weeks after cell delivery. Green shows peanut agglutinin (PA, green arrow), a distal tubular marker, and cyan shows a proximal tubular marker phaseolus vulgaris erythroagglutinin (PHA-E, cyan arrow). EPC showed mainly tubular engraftment (yellow arrow), while MSC tend to integrate into both proximal tubules (yellow arrow) and interstitial area (red arrow). Bottom: Both EPC and MSC improved RBF and GFR in pigs with RAS, yet MSC more effectively restored GFR. *p<0.05 vs. Normal, †p<0.05 vs. RAS. Scale bar=200µm
