Cell viability was assessed by MTT assay. Cells were seeded in 96-well plates and treated with celecoxib and/or imatinib for 24, 48 or 72 h. Then MTT was added and incubated for 4 h, followed by centrifugation at 1500 rpm for 5 min. Supernatants were removed and the remaining MTT dye was solubilized with 200 μl DMSO. The optical density was measured at 490 nm using a multi-well plate reader (Micro-plate Reader; Bio-Rad, Hercules, CA).
