Living Lilium pollen tube imaged with DIC optics. Shown is the growing tip with the apical region devoid of cytoplasmic organelles. Other images in the group reveal the distributions of cytoskeletal ...

Cultured HeLa cells were arrested in metaphase using nocodazole, immunostained for Plk1, CREST, and gamma-tubulin, and counter stained with DAPI. Images are maximum Z projections of convolved widefiel...

Cultured HeLa cells were arrested in metaphase using nocodazole, immunostained for Sgo1 or Myc Myc, and counter stained with DAPI. The montage illustrates the effect of restoring Bub1 or Bub1-T609A to...

Cultured HeLa cells were arrested in metaphase using nocodazole, immunostained for Plk1, INCENP, or CREST and Myc, and counter stained with DAPI. The montage illustrates the effect of RNAi depletion o...

Cryopreserved rabbit skeletal muscle cells were revived and stained for actin (in red) to reveal cytoskeleton and DAPI (in blue) to label nuclei.

Cryopreserved rat astrocytes were revived and stained for GFAP (in red) to reveal cytoskeleton and DAPI (in blue) to label nuclei. GFAP mutations and intracellular accumulation have been proposed to p...

The events of meiosis I in a living insect spermatocyte beginning at metaphase I with bivalents at the spindle equator followed by anaphase, segregation of half-bivalents diakinesis and commencement o...

Confocal fluorescence time-lapse imaging of a mitotic Drosophila S2 cell expressing GFP-tubulin and treated with 100 nM taxol for 1 h before imaging to induce assembly of monopolar spindles. Images w...

Confocal fluorescent time-lapse imaging of bipolar spindle collapse induced by 1 uM taxol in a mitotic Drosophila S2 cell expressing GFP-tubulin. Images were recorded at 120 sec intervals using a sp...

The events of meiosis I in a living insect spermatocyte beginning at metaphase with meiotic bivalents at the spindle equator followed by anaphase , segregation of bivalents to the spindle poles and t...
