qPCR analysis of astrocytic markers in COs at week 15. Y-axis indicates relative expression fold change. Data are represented as mean ± SEM. Statistical significance was determined using one-way ANOVA with Tukey's multiple comparisons test (WT: n=4 from 1 batch, KO: n=4 from 1 batch, W-AAV: n=4 from 1 batch)   qPCR analysis of astrocytic markers in COs at week 24. Y-axis indicates relative expression fold change. Data are represented as mean ± SEM. Statistical significance was determined using one-way ANOVA with Tukey's multiple comparisons test (WT: n=4 from 2 batches, KO: n=3 from 2 batches, W-AAV n=3 from 1 batch).   Data information: n.s (non-significant), *p ≤ 0.05, **p ≤ 0.01, ****p ≤ 0.0001.
