Conditioned media from ciliated GBM cell cultures promotes the proliferation of ciliated GBM cells. a Ciliated L0 GBM cells were exposed to purified conditioned media collected from either regular/wild-type (WT) ciliated L0 cell cultures (putatively containing cilia and extraciliary vesicles) or cilia-defective (KIF3A^−/− or IFT88^−/−) L0 cell cultures (putatively containing extraciliary vesicles only). b Bar graph shows MTT enzymatic activity, expressed as a percent of WT control. Statistics were performed using a one-way ANOVA with Bonferroni post hoc test
