c, VX680 (0.5 μM, a concentration that will specifically allow neuronal differentiation) was used to inhibit Aurora A activity. Bar diagrams below show quantifications. Compared to DMSO-treated control NPCs, a higher proportion of VX680 treated NPCs are ciliated (***p<0.001), exhibiting longer cilia (***p<0.001) and show Tuj1 positive neurons (***p<0.001). Error bars are s. e. m. For ciliated cells and cilium length: n = 3 independent experiments. 164 cells for DMSO-treated and 77 cells for VX680-treated. For NPC differentiation: n = 4 independent experiments. 286 cells for DMSO-treated and 118 cells for VX680-treated. Scale bar 1 μm.
