Fig. 2. The effect of pharmacological inhibition of actin assembly on ciliogenesis. (A) First nine panels from left: photomicrographs showing actin (phalloidin), basal body (
-tubulin) and cilia (
-tubulin-IV) localization in mTEC cultures at ALI day 3, obtained 1 day after treatment at ALI day 2 with vehicle, cytochalasin D or latrunculin B. Bar, 10 µm. Three panels on right: representative scanning electron micrographs (SEMs) of mTEC cultures on ALI day 4 obtained 1 day after treatment at ALI day 3. Bar, 1 µm. (B) Percentage of cells containing basal bodies localized at the apical membrane as a proportion of total cells containing basal bodies at the apical membrane or within the cytoplasm (identified by immunostaining for
-tubulin). Data are the mean ± s.d.; *P<0.05, significance compared with vehicle. (C) The percentage of cells with apical cilia (identified by immunostaining for
-tubulin-IV) as a proportion of all cells (identified by nuclear staining with DAPI). Data are the mean ± s.d.; *P<0.05, significance compared with vehicle.
