Drug efficacy in the in vivo Gelfoam angiogenesis assay. Bar graphs show the vessel length ratio on the day of measurement relative to day 22, which was the day of OS-PDC implantation into the Gelfoam previously inplanted in the mouse. Bar graphs express the average vessel length ratio and error bars show ± standard deviation. Statistical analysis was performed using Steel–Dwass test. *P < 0.05. **P < 0.01.
