Surface pattern of P. tetraurelia in a region with two basal bodies in each cortical unit. This is a thin-frozen section labeled with immunogold showing the location of b-tubulin. The gold lies over t...

Human retinal pigmented epithelial (RPE) cells labeled for clathrin-coated pits (green), focal adhesions (red) and nuclei (blue). RPE cells stabily expressing 'clathrin light chain a' tagged with EGFP...

High resolution image of the surface pattern of P. tetraurelia in a region with two basal bodies in each cortical unit. This is a thin-frozen section labeled with immunogold showing the location of b-...

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...

Microtubules 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, Westphal and Tiggemann, J. C...

High resolution view of the contractile vacuole pore encircled on its cytosolic surface with microtubules. Other microtubules arise from these encircling microtubules and extend far out into the cell ...

Capillary endothelial cells from mammalian cardiac muscle caught in the act of fluid-phase micropinocytosis. Arrows indicate multiple sites where invaginaton along the membrane suggests vesicles formi...

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. ...

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...

Freeze fracture of the plasma membrane and outer alveolar membrane of the pellicle of V. microstoma. The surface of Vorticella is encircled by rings which follow the septa of underlying alveoli. In th...
