Zebrafish embryo stably expressing the microtubule-binding domain of ensconsin fused to three GFPs (EMTB-3GFP). Astral microtubules at metaphase are too short to contact the cortex, and the spindle fo...

This movie illustrates the early division up to the four-cell stage of a C. elegans embryo depleted of npl-4 through RNAi. The first C. elegans embryonic division of the P0 zygote is asymmetric and ge...

A confocal Z-stack from a transgenic Drosophila expressing the kinesin-5 motor KLP61F-GFP embryo during prometaphase phase 1. KOP61-F is required to prevent prometaphase spindle collapse driven by t...

Dynamics of spindle microtubules and chromosomes during cycle 11 in a transgenic Drosophila embryo expressing GFP-tubulin (green) and histone-RFP (red). Only a single confocal plane containing the cen...

A confocal 4D-stack from Cycle 11 in a transgenic Drosophila embryo expressing gfp-tubulin (shown in green) and histone-rfp (shown in red). This image is original data contributing to Fig. S1. "Spindl...

A confocal 4D-stack from a transgenic Drosophila embryo expressing lamin-GFP (green) and injected with rhodamine-conjugated tubulin (red) and anti-lamin-B antibodies during prometaphase. The microinje...

This time-lapse series illustrates the early division up to the four-cell stage of a C. elegans embryo depleted of npl-4 through RNAi. The first C. elegans embryonic division of the P0 zygote is asymm...

This time-lapse series illustrates the early division up to the four-cell stage of a C. elegans embryo depleted of cdc-48 and atl-1 through RNAi. The first C. elegans embryonic division of the P0 zygo...

Anterior and posterior regions of a C. elegans embryo are determined by PAR protein distribution. PAR-2, shown in green marks the posterior region of the embryo and PAR-6, shown in red, marks the ante...

A confocal 4D-stack from a transgenic Drosophila embryo expressing lamin-GFP (green) and injected with rhodamine-conjugated tubulin (red) during prometaphase shows normal elongation of the spindle dur...
