a) RT‐qPCR results of NSCs on graphite patch under magnetic field at rotation speeds of 0, 100, 300, and 500 rpm at day 5. b) Immunofluorescence staining of Tuj1 and GFAP of NSCs on graphite patch under magnetic field at rotation speed of 0 and 500 rpm at day 5. Tuj1 was stained red. GFAP was stained green. While nuclei were stained blue by DAPI. c, d) RT‐qPCR of NSCs on culture plate or graphite patch without or with (+) a 500‐rpm magnetic field at c) day 5 and d) day 10. The data were expressed as the mean ± standard deviation (n = 3), as analyzed by a one‐way ANOVA, with Tukey's multiple comparisons test (nsp>0.05, *p<0.05, **p<0.01, ***p<0.001, and ****p<0.0001 compared to the culture plate group).
