High resolution image of the b-tubulin immunogold labeled microtubules that arise from the apex of the cytoproct ridge and pass to the spent DV membrane. Trichocyst and trichocyst tip included in this...

Adhesion dynamics in a migrating CHO K1 cell. CHO K1 cells expressing paxillin-mEGFP were plated onto coverslips that were preincubated with a solution of 5 ug/ml fibronectin overnight at 4o C. The ...

The contractile vacuole pore is encircled on its cytosolic surface with microtubules. Other microtubules arise from these encircling microtubules and extend far out into the cell where they provide st...

High resolution view of the bundles of microtubules that arise from along the elaborately woven blanket of the filamentous reticulum that covers the ribbed wall of the right side of the buccal cavity....

Transmission electron micrograph of spectrin in cell fractionation. Dr. V. T. Marchesi and colleagues took advantage of the high purity of red cell ghosts obtained by hypotonic lysis to analyze the p...

These two micrographs show the outer cell surface of the epithelial cell border in intestine (upper) and stomach (lower) tissue. This surface, called the glycocalyx, is composed of negatively charged...

This freeze fracture view of the pellicle of V. microstoma near the aboral end of the zooid shows the region where the width of each circumferential alveolus is narrower and thus the strings of fractu...

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...

High resolution view of the quadrulus membranelle (4 rows of cilia) in the buccal cavity of Paramecium tetraurelia labelled for tubulin. Microtubules of the axonemes of the cilia and the triplet fiber...

High resolution view of the bundles of microtubules that arise from along the elaborately woven blanket of the filamentous reticulum that covers the ribbed wall of the right side of the buccal cavity....
