b-tubulin immunogold labeled microtubules arise from the apex of the cytoproct ridge and pass to the spent DV membrane. Trichocyst and trichocyst tip included in this image. TEM taken on 7/5/96 by R. ...

A bundle of microtubules that arises from a basal body adjacent to the cytoproct comes to lie along a spent DV-IV. The assumption is that movement generated by molecular motors propels the spent vacuo...

Immunogold labeled microtubules next to the cytoproct radiate from basal bodies and also from the tip of the cytoproct. These microtubules lie along the approaching spent DV. b-tubulin immunogold labe...

In this colchicine-treated cell, used in an attempt to disrupt its microtubules, we found that microtubules already formed are not disrupted in Paramecium. This open cytoproct shows the microfilaments...

High resolution image of immunogold labeled microtubules next to the cytoproct radiate from basal bodies and also from the tip of the cytoproct. These microtubules lie along the approaching spent DV. ...

Single microtubules extend into the cytoplasm from the tips of the cytoproct ridge. These are thought to come to lie along the surface of the approaching DV-IV and to pull the ridge down against the D...
