Conditioned media from ciliated GBM cell cultures does not promote the proliferation of cilia-depleted GBM cells. Cilia-depleted KIF3A^−/− (a) or IFT88^−/− (b) L0 GBM cells were exposed to purified conditioned media collected from either wild-type WT, KIF3A^−/−, or IFT88^−/− L0 cell cultures. 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
