Figure 6.

The vascular-like structures in the cell/scaffold compounds of Groups 20S (A–C) and T (D–F) expressed CD31 at 2 weeks (A, D), 4 weeks (B, E), and 6 weeks (C, F) of culture in vivo. The new vessels resulting from the transplanted BMSCs could easily be detected by fluorescence microscopy due to their GFP-positive signal. The typical capillary-like tubules was formed in the constructs of Group 20S (yellow arrow). The nuclei were stained with DAPI (blue) (mean±SD, *p<0.05). Scale bar: 100 μm. Quantitative analysis of the microvessels in cells/scaffold compounds was shown in (G). GFP, green fluorescent protein.
