Differentiation and reversal of differentiation. Neurospheres (Nsp), differentiated to adherent cells (Diff) in 10% serum-containing medium and reverted back to a de-differentiated state (Diff-Nsp) after 14 days in stem-cell medium, (A) BG5 and (B) BG7 primary tumors. (C) Bar graph showing Nsp diameter in Nsp (black) and Diff-Nsp (gray) in BG5 and BG7 glioblastoma (GBM) cells. Data represent mean ± SD of n = 3 independent experiments per GBM patient-derived line. One-way ANOVA, Bonferroni’s multiple comparison test, ****P < 0.0001. Western blot showing glial acidic fibrillary protein and GAPDH in Nsp, differentiated, and de-differentiated Nsp (D) BG5 and (E) BG7 GBM cells.
