A Heparan Sulfate-Binding Cell Penetrating Peptide for Tumor Targeting and Migration Inhibition

Figure 2

Inhibitory effect of CPPecp on CT-26 cell migration. CT-26 cells were pretreated with CPPecp or EDN^32–41 at indicated concentration in serum-free RPMI-1640 medium at room temperature for 30 min and then seeded onto the upper side of transwell insert membrane at 37°C for 18 h. Number of migrated cells without CPPecp or EDN^32–41 treatment was set as 100%. The data represents means ± SD (standard deviation) of three independent experiments. ^*; ^**; ^*** compared with control.
