Centrioles are MT cargo. (A and B) Super-resolution imaging reveals a close relationship between centrioles (PLP; red) and MTs (gray) in PCs (A) and NBs (B). Scale bars: 5 µm; inset 1 µm. (C and D) Centrioles (cyan) move on the MTs (red) in PCs (C) and NBs (D). Scale bar: 2 µm. Fluorescence transgenes are as indicated on left. (E) PCs treated with SiR-Tubulin showing centrioles (arrowheads) moving along MTs and switching tracks. Scale bar: 2 µm. Time stamp: mm:ss.
