Sixteen cell stage Zebrafish embryo. The first frame shows cells at metaphase. The sequence covers the next four cell cycles. In each prophase, there is a rapid onset of yolk platelet motility. Yolk m...

Spinning disk confocal time-lapse imaging of the first mitosis in a C. elegans embryo expressing GFP-CeCENP-A in strain OD101. During prophase, discrete foci of GFP signal within the nucleus coalesce ...

Spinning disk confocal time-lapse imaging of the first mitosis in a C. elegans embryo expressing GFP-KNL-2 in which CeCENP-C was depleted by RNAi in strain OD31. Discrete foci of GFP signal within the...

Spinning disk confocal time-lapse imaging of mitosis in asynchronous HeLa cells transfected with control, nontargeting siRNA oligonucleotides, or siRNA oligonucleotides targeting HsKNL2. Top, nontarge...

Spinning disk confocal time-lapse imaging of the first mitosis in a C. elegans embryo expressing GFP-KNL-2 in strain OD31. As seen for GFP-CeCENP-A (CIL 28780), discrete foci of the GFP signal within ...

Frog (Xenopus laevis) egg arrested in metaphase of mitosis. Note the tiny metaphase spindle on the top left of the egg. Eggs were fixed in 90% MeOH; 10% (H20 500mM EGTA) and stained for DNA with YoP...

Image shows a metaphase spread revealing the 46 human chromosomes (blue). Telomeres have been labeled using PNA-FISH and appear as pale dots at the ends of each chromatid.

Scanning probe/atomic force microscope image of human chromosomes in a metaphase spread. Additional scanning probe images of chromosomes are available as CIL 39000, 38915, and 39013.

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