Effects of PSH on U251 cell viability, migration and invasion. (A) Cells were treated with 0.01, 0.1, 1, 10 and 100 µg/ml PSH for 24, 48 and 72 h, and the cell viability was measured by Cell Counting Kit-8 assay. (B) Effects of PSH on cell migration. After confluence was reached, cells were treated with 25, 50 and 100 µg/ml PSH, and the wound healing assay was performed. (C) Effects of PSH on U251 cell invasion. (D) Quantitative data of the cell invasion assay results. ^**P<0.01 vs. control. PSH, Paris saponin H; Con, control.
