FIG. 3.

Immuno-histochemical evaluation of the scaffolds harvested at day 7. Angiogenesis and vasculogenesis visualized with anti-mouse and anti-human CD31 antibodies, respectively, in 200-μm thick scaffold sections. One million EPCs were seeded in each scaffold. The scaffolds with VEGF were loaded with 10 μg of the growth factor; the scaffolds with heparin were cross-linked for 15 h. Scale bar=500 μm. Color images available online at www.liebertonline.com/tea
