Migration assay by scratch-wound healing on F1-treated glioblastoma (NG97) cells. a–d Control (untreated cells); 72 h after the scratch, it was completely closed. e–h When exposed to F1 at 0.1 µg/ml, the cells showed a delay in the wound closure, filling it only after 72 h. i–l Cells treated with F1 (1.0 µg/ml), showed the most relevant delay in wound closure and did not fill the scratch even after 72 h. m–p F1 at 10 µg/ml also induced a delay in wound closure, but the cells could fill it after 72 h. Results of three independent experiments. Bars = 50 µm
