Sudden change in direction of gliding MTs with segregation of tapered PFs from the leading end. (a) Time-lapse images showing splitting of a MT at the tapered leading end during gliding motion. The red arrows show moving direction of gliding MTs and PFs separated from leading end of the MT. Scale bar: 500 nm and frame rate: 0.2 s/frame. (b) Schematic model showing sudden directional change of MT with segregation of a PF from the tapered leading end of the MT.
