Exogenous recombinant human BMP7 promotes human LN18 glioblastoma cell transmigration and migration. (A) Human LN18 glioblastoma cells were kept as the controls or treated with BMP7 (25, 50, and 100 ng/mL) for 24 h and then the transmigration capability of cells was determined by the transwell assay. (B) Human LN18 glioblastoma cells were kept as the controls or treated with 50 ng/mL BMP7 for 0 and 24 h and then the migration capability was determined by the wound-healing assay. Results in (A,B) are representative of three independent experiments with similar results. Statistic data in (A,B) are mean ± SEM from three independent experiments. (A,B) *, p < 0.05 vs. CL group (A) and CL-0 h group (B). (B) #, p < 0.05 vs. CL-24 h group. Scale bars in (A,B) are 100 μm.
