This group represents a serial series of sections. At the level of this section the macronucleus, cytopharyngeal tube, food vacuoles, and perioral membranelle are evident. TEM taken on 3/12/71 by R. A...

This group represents a serial series of sections. At the level of this section, the bottom of cytopharyngeal tube with one cilium remaining. End of macronucleus, three membranelles of the pek, and ma...

Mouse myoblast cells were engineered to express GFP-PCNA (proliferating cell nuclear antigen) as a marker for replication factories, and also immunostained for DNA ligase. DNA was localized using Hoec...

Ema localizes to endosomes. Third instar larval garland cells expressing Ema-GFP fusion protein and stained for the multivesicular body ESCRT protein Hrs (red). Ema does not localize to MVB. Wandering...

Fluorescence image of tripolar mitosis in a liver cancer cell line. Normally, dividing cells form a single metaphase plate of paired chromosomes which are pulled apart by opposing microtubule spindle...

The deep fiber is associated with the cytopharyngeal membrane (see Smith and Bunse, Trans. Am. Microsc. Soc. 102:264-271, 1983). This membrane has acidosome-like vesicles docked at its cytosolic surfa...

This confocal micrograph shows wheat stigma hairs (blue) infected with ergot fungus (shown in light pink). The stigma hairs are part of the female reproductive organs of the plant. When a pollen grain...

Shown are 0.5 micrometer thick confocal image of midplane sections of synchronized 3T3 fibroblasts pulsed for 2 min with CldU and labeled with FITC (green) followed by a variable chase time, and a sec...

Shown is a 0.5 micrometer thick confocal image of a midplane section of a 3T3 fibroblast pulsed for 5 min with BrdU and immuno-labeled with anti-BrdU antibodies. Replication is confined to discrete si...

Mouse myoblast cells were engineered to express GFP-PCNA (proliferating cell nuclear antigen) as a marker for replication factories, and also immunostained for the DNA methylase Dnmt1. DNA was localiz...
