SAHA and NaB inhibit adult mouse NSC proliferation in culture and arrest cells in G1 phase of the cell cycle. (a) EdU flow cytometry of live cell-gated adult mouse NSCs demonstrates SAHA (**p < 0.01) and NaB (***p < 0.001) significantly inhibit DNA synthesis. (b) Analysis of DNA content by flow cytometry reveals significant accumulation of adult mouse NSCs in G1phase of the cell cycle following SAHA (*p < 0.05) and NaB (*p < 0.05) treatment. (c) Correspondingly the proportion of cells in G2/M phase is significantly reduced following SAHA (*p < 0.05) and NaB (*p < 0.05) treatment. (d) Fluorescence micrographs of HDACi/vehicle treated adult NSCs pulse-labeled with EdU for flow cytometry. Scale bar = 50 μm. Statistical comparisons performed using one-way ANOVA with post hoc Newman-Keuls multiple comparison tests.
