A Immunofluorescent images for Tuj-1, OSP and GFAP expression by NSCs seeded on different groups. DAPI staining for nuclei (blue) and Cy3-conjugated secondary antibody for protein (red), scale bar lengths are 50 μm. B Axon length of new neurons and the proportion of new neurons, oligodendrocytes and astrocytes in each group, P < 0.05, error bars represent standard deviation for n = 3
