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...

The micronuclear separation spindle. Nuclear pores are not empty perforations but are closed by nonetchable material. The separation spindle must elongate as microtubules lengthen and/or slide against...

Quick-freeze deep-etch of an ampulla. The P-fracture face has numerous IMPs. The microtubular ribbon now forms two bands next to this ampulla. The ribbons will split into additional bands as they pass...

A post ciliary microtubular ribbon extends from the proximal left side of the basal body and arches toward the cell surface where it ends near the longitudinal microtubular ribbon at the crest of the ...

A circular depression on the dorsal surface of the cell marks the expulsion site of a contractile vacuole. This is referred to as the contractile vacuole “pore.". Microtubules encircle the pore. Tr...

Up to three basal bodies have been seen in various stages of development near a mature basal body/cilium complex. In this micrograph 2 new basal bodies are present next to 2 cilia and 3 are forming ne...

Bundle of microtubules supporting the oral apparatus of Coleps. This micrograph shows the detail of microtubular cross-bridging within one of these rods. Microfibrillar bridges are located at 22nm int...

Detail of CV pore. Microtubules encircle the pore wall and other microtubules radiate out from the pore toward the CV membrane. TEM taken on 3/27/69 by R. Allen with Philips 300 operating at 60kV. Neg...

A high resolution view of the tubulated CV membrane attached to ampullae 2, 3, 4 and 5 of the CVC. The tubules lie against the ribbon of microtubules as well as form a large mat lying inward (centrifi...

A high resolution image of a bundle of microtubules supporting the oral apparatus of Coleps. This micrograph shows the detail of microtubular cross-bridging within one of these rods. Microfibrillar br...
