Cilia driven transport. (A) Transport of 1-μm fluorescent beads at the apical surface of a washed epithelium. The image is a standard deviation projection over 50 images. Scale bar, 200 μm. (B) Local transport. Trajectories are obtained by tracking 1-μm beads. Scale bar, 20 μm. (C) Rotational transport of mucus spanning the whole chamber (same sample than in A). The image is a standard deviation projection over 50 images. Scale bar, 200 μm.
