FGF1 protects the cytoskeleton and promotes cell polarization in vitro. A, Immunofluorescence images show ace‐tubulin (green) in PC12 cells subjected to H₂O₂ (100 μmol/L) and treated with AAV‐FGF1. Scale bar = 50 μm. B, Quantification of fluorescence (axonal length of PC12 cells) from A, ns means “no significant difference”; *P < .05. C, Representative Western blot results of microtubule protein for each group of PC12 cells. D‐E, Quantification of Western blot data from C, ***P < .001; **P < .01
