Cross-linking and depolymerization activities delivered to MT minus-ends generate robust spindles. Bipolar, fluxing spindles with focused poles formed in simulations containing MTs (red and green), a cross-linking force, kinesin-5, minus-end delivery of oligomeric NuMA (yellow and cyan), and kinesin-13 MT depolymerization activity in the vicinity of NuMA. A high density of minus ends (white) can be observed at each spindle pole. Bar (blue), 5 ┬Ám.
