Q-PCR analysis of pluripotency, NSC self-renewal, neuronal and glial lineage marker genes in hNSC H9 cells and nhNPCs. Relative expression in hNSC H9 cells and nhNPCs of: (A) pluripotency markers; (B) NSC self-renewal markers; (C) neuronal lineage defining markers; and (D) glial lineage defining markers. Relative expression normalised to 18 S, error bars=SD, statistical significance: ⁎p<0.05, ⁎⁎p<0.01, ⁎⁎⁎p<0.001.
