Sand dollar embryos expressing GFP-H2B going thru stages of mitosis.

Fluorescent micrograph showing the mitotic spindle, which is composed of microtubules. During cell division the chromosomes duplicate and are pulled to opposite poles by the spindle, once the chromoso...

Time lapse movie of a developing sand dollar embryo expressing GFP-histone H2B. The movie shows several rounds of mitoses.

Sand dollar embryos expressing GFP-H2B going thru stages of mitosis. Video is animated with the cursor indicating the stages of mitosis and the morphological characteristics of the stage during the t...

Microtubules in sand dollar embryos expressing three tandem Cherry fluorophores fused to the ensconsin microtubule-binding domain (EMTB-3C). Video demonstrates microtubule dynamics during process of ...

Pig epithelial (LLC-PK1) cells undergoing mitosis. Image shows microtubules (green) and chromosomes (purple) and was collected using a spinning disk confocal and deconvolution microscopy. Honorable M...

Eight-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 nocodazole at time 00:...

16-cell purple urchin 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. The top left cel...
