Microtubules that form the stationary lattice of muscle fibers are dynamic and nucleated at Golgi elements

Shown is an intravital time-lapse sequence (1 frame per 3.8 sec) of five muscle fibers expressing different levels of EB3-GFP. The plane of focus intersects the fibers at different depths. To view the video at the intended speed, choose the option "make a movie" and use 10 fps, which will give an acceleration factor of 40. Scale bar=10 μm.
