The representative images of wound-healing assay in six groups. SCC-25 cells (left part) and CAL-27 cells (right part) were treated with HLJDD 5 mg/mL, HLJDD 2.5 mg/mL, HLJDD 1.25 mg/mL, paclitaxel 6 μg/mL and cisplatin 5 μg/mL for 24 h, respectively. All images both before administration and after administration were taken under microscope (original magnification, ×40). The blue dotted line represented the area scratched by the 1000 µL-pipette tips. The statistics were expressed as Mean ± SEM, n = 7 (SCC-25 cells). * p < 0.05 vs. control group. The statistics were expressed as Mean ± SEM, n = 4 (CAL-27 cells). *** p < 0.001, **p < 0.01, * p < 0.05 vs. control group
