Fig. 5: Specific effects of irradiation and lithium treatment on hNSPCs, on gene expression, for genes linked to negative regulation of gliogenesis.

Gene expression fold change compared to untreated and normalized to GAPDH, for selected genes, a GREM1 (n = 7), b BMP4 (n = 8), c SMAD7 (n = 8), d SOX10 (n = 5), e SOX5 (n = 5), f PTN (n = 5). One-way ANOVA and paired t-test, *p < 0.05, **p < 0.005. Error bars represent mean and SD.
