Matrigel invasion assay. Glioblastoma cells were treated with parthenolide, and cell invasion was assessed using a Matrigel invasion assay. (A) Representative U87MG cell data. (B) Number of invading glioblastoma cells relative to control. The number of invaded cells decreased as the concentration of parthenolide increased. Bar = 100 μm. Data is presented as mean ± SD (n = 3). Points indicate bars + SD; * indicates p < 0.0001; ** indicates p < 0.01.
