Movie 7

A representative example of computer simulation is shown without KT sliding (associated with Figure 5B). Three-dimensional simulations are projected into X-Z and X-Y planes. KTs (dots) are colored as in Figure 5A. MT extension following KT-dependent rescue is shown in a dashed line (Gandhi et al., 2011). A gray line, which connects a KT (dot) to a MT extending from a spindle pole (black line), represents a KT-derived MT that facilitates KT loading onto a MT extending from a spindle pole (Kitamura et al., 2010).
