Vascular quantification of healing fractures of WT and MMP-9 deficient mice.

<p>Quantitative assessment of microfil based angiography surrounding the healing fracture. No statistical differences in vascularity were identified between wild type and MMP-9 deficient mice at any time point for either vascular volume (mm³) or vessel thickness (mm). 7d- WT: N = 4, MMP-9: N = 3; 10d- WT: N = 4, MMP-9: N = 3; 14d- WT: N = 5, MMP-9: N = 6; 21d- WT: N = 4, MMP-9: N = 6; 28d- WT: N = 7, MMP-9: N = 6. Individual time points were assessed by non-parametric t-tests. Alpha = 0.05.
