GFAP is necessary for the modulation of a subset of morphological characteristics in astrocytes induced by the CNT modalities. (a) Images of live wild-type and GFAP KO astrocytes in culture plated onto the PEI-coated coverslips in the absence and presence of the SWCNT-PEG solute (5 μg/mL) and onto the 60 nm thick SWCNT-PEG films, loaded with the vital fluorescent dye, calcein. Scale bar, 20 μm. (b) Summary graphs showing the median effects of the CNT modalities on the morphology of astrocytes. The number of astrocytes studied in each condition is given in parentheses in the form factor graph. *p < 0.05, **p < 0.01. Other annotations as in Figure 1.
