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 ...

Z-series image of mouse ES cells carrying an alpha-globin BAC transgene array (clone 7d) transduced with a lentivirus containing an expression cassette for EGFP-LacI. EGFP-LacI binding (green) to the...

In one experiment in which electric shock was applied to Paramecium cells to trigger trichocyst discharge the macronucleus in one cell was observed to undergo morphological changes of two types. First...

Early transmission electron micrographs showing pore details in negatively stained preparations of nuclear envelopes. Upper panel shows the pronounced 8-fold symmetry in the closely spaced pores of t...

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...

Transmission electron micrograph illustrating the 'classic' appearance of the nucleus in osmium tetroxide fixed material. In this pancreatic acinar cell nucleus, the only prominent feature is the lar...

Transmission electron micrograph of a bone marrow orthochromatic erythroblast from guinea pig showing terminal differentiation in erythrocyte formation. Accompanying the cessation of most transcriptio...

The transmission electron micrograph shows stacked annulate lamellae from a human Sertoli cell. Annulate lamellae consist of sheets of membrane containing closely packed structures resembling nuclear...

Transmission electron micrographs showing annulate lamellae from a frog oocyte. Annulate lamellae consist of stacked sheets of membrane containing closely packed structures resembling nuclear pores a...

Transmission electron micrographs. The upper panel shows a section through a frog nucleated erythrocyte. The nucleus is largely filled with heterochromatin which appears to have a fibro-granular stru...
