The expression level of cellular differentiation marker proteins in HT-22 cells during the treatment of agarwood ethanol extract. (A) Representative western-blot images of NeuN, BDNF, Syn, Sigma-1 and GAP43 in HT-22 cells. (B) The graph represents the semi-quantified data using Image J. The data are obtained from three independent experiments and expressed as the means ± SEM (n = 3). One-Way ANOVA, followed by Dunnett’s post hoc test, evaluated the statistical differences; *p < 0.05, ***p < 0.001 compared with control group.
