Figure 2. Resistance of CD133+ cells to TMZ.
Sorted U87 and T98G cells were transfected with anti-miR-9 or untransfected. The cells were treated with 200 μM TMZ. After 72 h, cell viability was assayed by CytoTox 96® LDH release. The results are presented as % cell death±SD, n ¼ 4. *p < 0.05 vs. CD133− cells. ** p > 0.05 vs. untransfected CD133+ cells.
