Dual-channel spinning-disk confocal time-lapse movie showing kinetochores (Alexa488 labeled CENP-A antibody) in anaphase (red) relative to poleward microtubule flux. Fluorescent speckle microscopy (FS...

Microtubules in live urchin embryos expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). Microtubules approach the cortex everywhere before an...

Microtubules in sand dollar embryo expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). Vegetal view, 28-cell sand dollar embryo show astral mi...

16-cell purple urchin embryo expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). The embryo was treated with 20 µM trichostatin A (TSA), an i...

Single-plane sequences of anucleate, centrosome-containing cytoplasts (sand dollars) expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). This...

Time lapse of mCherry-tubulin by wide-field epifluorescence at the coverslip interface (left), mCherry-tubulin by TIRF (middle), and myosin-GFP by TIRF (right). The acquisition of Cherry-tubulin by TI...

TIRF time lapse of mCherry-tubulin (left), myosin-GFP (middle), and overlay (myosin in green and tubulin in red; right) in a cell with a monopolar spindle from metaphase to anaphase. The S2 cells are...

Daughter micronucleus in anaphase of a dividing cell of Didinium nasutum. The chromosomes are compacted into one large heterochromatic body. Remnants of the mitotic division spindle remain inside the ...

6-cell sand dollar embryo expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). 10 µM nocodazole was added at time 00:00, at which time three o...

TIRF time-lapse imaging of myosin-GFP (left) and mCherry-tubulin (right) in an S2 cell depleted of kinesin-6 (Pav) by RNAi. Myosin-GFP localization to the equator and loss from the poles does not occu...
