Endogenous nNOS is required for neuronal differentiation of embryonic NSCs. The monolayer-cultured NSCs from nNOS-/- and WT embryonic mice differentiated for 4 days and then were fixed for stain. (A) Statistical graph showing the ratio of GFAP+ astrocytes. (B) Representatives of GFAP-labeled cells. (C) Statistical graph showing the ratio of β-III-Tubulin+ neurons. (D) Representatives of β-III-Tubulin+ cells. Nuclei were counterstained with Hoechst 33258. Scale bars = 50 μm. Data are mean ± SEM (n = 3); p<0.05 as compared with WT. GFAP, glial fibrillary acidic protein; nNOS-/-, gene knockout of neuronal nitric oxide synthase; WT, wild-type.
