APS and the combination of APS and HCPT reduce the migration ability of H460 cells. (A) Migration of H460 cells with or without treatment with 0.05 mg/ml APS, 0.2 µM HCPT or the combined agents was measured using a wound-healing assay. (B) Quantification of the wound gaps 24 h following induction of the wound. Images were captured using an optical microscope at a ×40 magnification. Data are presented as the mean ± standard error of the mean of three independent experiments, with 10 random fields counted in each chamber. Scale bar, 200 µM. APS, Astragalus polysaccharide; HCPT, 10-hydroxycamptothecin. ^**P<0.01 vs. control.
