HDACi treatment under proliferation culture conditions leads to long-term changes in differentiated cell fate. (a) Immunofluorescence labeling of NeuN, GFAP and Olig2 cell fate markers reveals reduced expression of GFAP (*p < 0.001) and Olig2 (*p < 0.05) in adult mouse NSCs treated with SAHA for 48 hours under proliferation culture conditions and then induced to differentiate for 14 days in culture (two-way ANOVA with Bonferroni post-tests). (b) Western blot of β-catenin protein in nuclear and cytoplasmic fractions of adult mouse NSCs treated with HDACi/vehicle control under proliferation culture conditions. Gapdh and lamin A/C blots are included as loading controls. (c) SAHA and NaB do not significantly alter nuclear/cytoplasmic levels of β-catenin in adult mouse NSCs. Histogram of β-catenin Western blot signal intensities normalized to loading controls (n = 4).
