(B) HeLa cells depleted of ALIX or not were immunostained with anti-α-tubulin (red), anti-Pericentrin (green) and Hoechst (blue). Representative confocal images are presented. Scale bars, 5 μm. The graph shows MT intensities as percentage of control cells (±S.E) obtained from 99 control and 90 ALIX siRNA transfected cells (data obtained from six separate experiments). Significant differences are noted as *p<0.05 and ***p<0.001 (Student's t-test)
