APS and combination treatment of APS and HCPT reduce the migration ability of H1299 cells. (A) Migration of H1299 cells with and without treatment with 0.1 mg/ml APS, 0.1 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 ×40 magnification. Data are presented as the mean ± standard error of the mean of three independent experiments, with ten random fields counted in each chamber. Scale bar, 200 µM. APS, Astragalus polysaccharide; HCPT, 10-hydroxycamptothecin. ^**P<0.01, vs. control.
