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

A confocal 4D-stack from a transgenic Drosophila embryo during prometaphase expressing lamin-GFP (green) and injected with rhodamine-conjugated tubulin (red) and the lamin-B tail dominant negative sub...

Mitotic PtK1 cell microinjected with X-rhodamine-labeled tubulin and Alexa 488-labeled CENP-F antibodies to fluorescently label kinetochore fibers (red) and kinetochores/spindle poles (green), respect...

Early embryonic divisions in Drosophila are syncytial. Nuclei undergo mitosis synchronously for the first 14 nuclear cycles, followed by cellularization (Foe and Alberts, 1983). At nuclear cycle 10, n...

This movie is of a Drosophila melanogaster early embryo (cycle 12) expressing GFP-tubulin (green) and injected with Rhodamine-labeled histones (red) and 8mg/ml RanT24N, a dominant negative inhibitor o...

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...

A confocal 4D-stack from a transgenic Drosophila embryo expressing lamin-GFP (green) and injected with rhodamine-conjugated tubulin (red) during surrounding the prometaphase (phase I and II) spindle. ...

Tripolar mitosis in liver cancer cell line. Normally, dividing cells form a single metaphase plate of paired chromosomes which are pulled apart by opposing microtubule spindles. This sequence shows p...

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 ...

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...
