Fluorescent micrograph of epithelial cells from the bladder wall. The cells were isolated immediately after collection of a urine specimen and are not fixed. The image was taken using a standard epi...

Scanning electron micrograph of the inside of a cancer cell. This cell originates from a squamous cell carcinoma, a type of skin cancer. The cell has been frozen and split open to reveal its nucleus.

In an enlargement of a pronucleus in the chromatin material appears as sparsely scattered opaque bodies, as may be expected of a haploid nucleus, in a medium dense nucleoplasm. The nuclear envelope of...

Nuclear envelope and spindle dynamics when the nucleus moves into the neck of kar9delta mutant cells arrested in S phase. Movie plays at 100x real time and is movie S6 in Proc Natl Acad Sci. 2009. 10...

During self conjugation two cells from a 6-day old culture come together, bridges are formed between them and haploid products of meiotic division of their micronuclei are exchanged between the mating...

Nuclear envelope and spindle dynamics when the nucleus moves into the neck of kar9delta mutant cells arrested in S phase. Movie plays at 100x real time and is movie S5 in Proc Natl Acad Sci. 2009. 106...

Microtubule detachment from the spindle pole body in kar9delta nip100deltaCAP-gly double mutant cells arrested in S phase. Movie plays at 20x real time and is movie S8 in Proc Natl Acad Sci. 2009. 106...

Nuclear envelope and spindle dynamics when the nucleus moves into the neck of kar9delta Nip100deltaCAP-Gly double mutant cells arrested in S phase. In these cells, the spindle failed to enter the bud ...

Spindle oscillation in kar9delta cells arrested in S phase. In wild-type cells, the spindle moves in both directions through the bud neck; these movements coincide with lateral sliding of a cytoplasmi...

Timelapse movie of GFP-labeled microtubules in kar9delta cells (arrested in S-phase) combined with a deletion of the CAP-Gly domain of Nip100. The number of cells in which the spindle moved from the m...
