Angiogenic factors and cell engraftment.

<p>MSC, labeled with CM-DiI (red), were localized in medullary slides co-stained with DAPI nuclear stain (blue) and the tubular marker cytokeratin (green). MSC were observed mainly engrafted in the medullary interstitium (A). Representative immunoblots (B) and quantification of medullary expression of the angiogenic factors VEGF, FLK-1 (C) and hypoxia inducible factor, HIF1-α (D). (*p≤0.05 vs. Normal, ^#p≤0.05 vs. ARAS+PTRA+MSC).
