Oridonin Loaded Solid Lipid Nanoparticles Enhanced Antitumor Activity in MCF-7 Cells

Figure 6

Cell apoptosis of MCF-7 cells after treatment of different solutions (free ORI and ORI-loaded SLNs) at different concentrations (20 μM and 10 μM) for 24 h. Q1, Q2, Q3, and Q4 phases correspondingly stand for necrotic cells, late apoptotic cells, live cells, and early apoptotic cells (a). Values of apoptotic cells (Q2 and Q4) are presented by bar graph (b). *𝑃<0.05 versus control; **𝑃<0.01 versus control.
