SWCNT-PEG solute induces morphological changes in mouse cortical astrocytes. a Images of astrocytes in culture, treated with 1 μg/ml PEG, 5 μg/ml SWCNT-PEG or 30 μM Y-27632, and loaded with calcein, a vital fluorescent dye. Scale bar, 20 μm. b Summary graphs showing the median effect of the various treatments on astrocytic morphology, i.e. area, perimeter and form factor. Number of astrocytes studied in each condition is given in parentheses in the area graph. Asterisks indicate a statistical difference when compared to the untreated/control astrocytes. The other differences are marked by the brackets. Kruskal–Wallis one-way ANOVA (KWA) followed by Dunn’s test. *p < 0.05, **p < 0.01.
