a Fluorescence images of three representative cell-penetrating peptides (CPPs) in the different cell lines. Scale bar, 10 μm (amplification factor, ×200). b Comparisons of the positive rates of the cell lines showed that CPP2, a colon cancer line–homing peptide, had a higher mean positive rate than that of R8 or TAT (p < 0.05). aSignificantly different from CPP2 (p ≤ 0.05); bsignificantly different from R8 (p ≤ 0.05). c Statistical analysis showed that CPP2 had higher mean fluorescence intensity than both R8 (p < 0.05) and TAT (p < 0.05) in LoVo, SW480, and HCT116 cells. Comparisons of CPP2 vs R8 and CPP2 vs TAT showed no statistical significance in HL-7702 cells (p > 0.05). aSignificantly different from CPP2 (p ≤ 0.05); bsignificantly different from R8 (p ≤ 0.05)
