GSC neurospheres were dissociated to single cell suspension and transfected with either miR-10b inhibitor (labeled "miR-10b-i") or non-targeting control oligonucleotide, or treated with Lipofectamine 2000 only (Mock). Statistical significance of the difference was determined by Student's t test, with p-values < 0.001 indicated by three asterisks. Numbers of replicates and exact P-values are included in Appendix Table S4.A. Cell viability was monitored at day 5 after transfection as described in Materials and Methods.
