Fig. 5From: Ifosfamide-loaded poly (lactic-co-glycolic acid) PLGA-dextran polymeric nanoparticles to improve the antitumor efficacy in OsteosarcomaApoptosis analysis was detected by Annexin-V/PI staining. Apoptosis of a MG63 b Saos-2 cancer cells. The respective cell percentages in early and late apoptosis for different time period are presented in the bar graph. **p < 0.01 is the statistical difference in apoptosis between IFS and PD/IFS in both cancer cellsBack to article page
