Effect of curcumin on GBM Stem Cell Lines and non-stem Cell Lines. a GBM stem cells were treated with increasing concentrations of curcumin and viability was assessed 72 h later with MTS assay. b MTS viability assay was used to determine concentrations needed to induce 50% cell death (IC₅₀) in GBM stem cell lines. c MTS viability assay was used to determine concentrations needed to induce 50% cell death (IC₅₀) in GBM non-stem cell lines
