Mechanisms Underlying the Antiproliferative and Prodifferentiative Effects of Psoralen on Adult Neural Stem Cells via DNA Microarray
Figure 3
Effects of Psoralen on the differentiation of NSC. Single NSCs were seeded at a density of 50 cells/μL in PDL-coated 96-well plate in differentiation medium for 48 h without Psoralen (a, b) or with 100 nM Psoralen (c, d). Cells were subjected to primary antibodies of GFAP, TuJ1 and corresponding secondary antibodies and visualized with Alexa-conjugated 594 F(ab)′2 goat anti-rabit antibody and 488 Alexa-conjugated goat anti mouse IgG (H + L). The ratio of GFAP, TuJ1-positive cells against DAPI-stained cells was calculated. Psoralen significantly increased the GFAP-positive cells and decreased the TuJ1-positive cells (e). The same cells were performed using Western blotting. Psoralen significantly increased the GFAP, decreased the TuJ1 protein expression (f). Scale bars: 100 μm. Results were expressed as mean ± S.D. from three independent experiments. * versus control.
