The macronucleus contains microtubules that lie inside a seemingly intact nuclear envelope. Microtubules orient along the axis of macronuclear elongation in the form of small bundles. The section is i...

High resolution image of the dividing macronucleus shows it may be porous to microtubules. Segments of microtubules are found both outside and inside the nuclear envelope in this figure although one c...

High resolution image of microtubules that sometimes extend deep into the cytosol from the basal bodies. They serve to guide the trichocysts to their docking sites at the plasma membrane (see Plattner...

Time-lapse microscopy of a b-Tubulin GFP expressing mouse oocyte injected with siCo-5h, a control siRNA. Images were taken every 20 minutes. Times after the resumption of meiotic maturation and germin...

The dividing macronucleus may be porous to microtubules. Segments of microtubules are found both outside and inside the nuclear envelope in this figure although one cannot follow a single microtubule ...

High resolution view during division showing the micronucleus contains internal microtubules as well as a layer of b-tubulin, not in microtubular form, on or just inside the nuclear envelope. The sect...

During division the micronucleus contains internal microtubules as well as a layer of b-tubulin, not in microtubular form, on or just inside the nuclear envelope. The section is immunogold labeled wit...

A tangential section through the cell’s surface show the pairs of basal bodies in cross section. The ends of kinetodesmal fibers point anteriorly in the cell, the postciliary ribbons arise from the ...

Free microtubule sliding in cnm67delta mutant cells. Movie plays at 50x real time and is movie S11. Compare with movie S12 (CIL# 23602). Data analysis for movies S11 and S12 in Figure S4B of Proc Nat...
