The apoptosis effect of CPT-11-loaded DSPE-PEG2000 targeting EGFR liposome in vitro. A Flow cytometry was performed to assess the apoptosis effects of CPT-11, CPT-11-Lipo, EGFR-Lipo-CPT-11, and control; B–D Western blot results showing the protein levels of cleaved-caspase-3 and cleaved-caspase-9 from four different groups mentioned above and their gray value (**p < 0.01, ***p < 0.001)
