Live-cell imaging of the behavior of individual stable MTs. Related to Fig. 3. (A–C) Stills and schematic representations from live-cell imaging of StableMARK in U2OS cells depicting MT deformation, MT breakage (indicated by orange arrowhead), and partial MT depolymerization (indicated by orange arrowhead), respectively. (D) Kymograph of the partial depolymerization event is shown in C. Scale bars, 2.5 µm. Time, min:s.
