Quantitative analysis of immunofluorescence staining. a and b ALA and AHSO significantly enhance the frequency of astrocytes (GFAP) and oligodendrocytes (MBP). c ALA did not affect the differentiative activity of eNSCs into neurons, however, higher concentrations of AHSO (100 μM) significantly increased the frequency of β-III tubulin positive cells, in comparison to controls. The asterisks indicate statistical significance with respect to controls (*, p < 0.05; **, p < 0.01; ***, p < 0.001; and ****, p < 0.0001; one-way ANOVA followed by Tukey multiple test). Data are presented as means ± SEM. n = 15
