HDACi treatment results in increased histone H3 acetylation, reduced neurosphere formation and minimal toxicity in adult mouse NSCs grown in proliferation conditions in culture. (a) Western blot of whole cell extracts demonstrates SAHA and NaB treatment result in increased levels of acetylated histone H3 compared to vehicle controls. (b) Light micrographs of HDACi/vehicle treated cultures illustrate the paucity of neurospheres in HDACi-treated cultures. (c) Quantitative analysis confirms SAHA and NaB inhibit the formation of neurospheres (diameter ≥ 50 μm) and increase the prevalence of small cell clusters (≥ 4 cell, diameter < 50 μm). (d) Flow cytometry using LIVE/DEAD cell stain confirms SAHA and NaB are minimally toxic compared to vehicle controls (n = 3). Scale bar = 100 μm.
