Figure 4.

BMSC distribution (blue) at the center of the scaffolds in the experimental and control groups at 1 h (A, D), 7 days (B, E), and 14 days (C, F) of culture in vitro. Histological sections were stained with PI to identify the cell nuclei (red). Scale bars: 150 μm. (G) Shows the statistical analysis of the total number of BMSCs at the center of the scaffolds in all groups (mean±SD, *p<0.05, **P<0.001). PI, propidium iodide.
