Bar-dot graph reporting transcript levels of the inflammatory marker gfap in astrocytes plated on ITO, rGO and GO before (NO STIM) and after (STIM) electrical stimulation. The y value corresponds to the levels of expression of gfap mRNA normalized with respect to the relative values for -actin. Data are presented as mean s.e.m. N = 4 per condition, in triplicate (pooled). Normalized gfap mRNA levels are for ITO NO STIM 1 0, for ITO STIM 0.5 0.01, for rGO NO STIM 1 0, for rGO STIM 0.6 0.1, for GO NO STIM 1 0 and for GO STIM 0.9 0.2. Statistical significance was calculated via one-way ANOVA with Bonferroni post-test. P values are reported in the graph when P 0.05, which was considered significant. No statistically significant difference was observed between GO NO STIM and GO STIM ( P = 0.6).
