Freeze fracture image of the E-face of rat bladder lumenal membrane. The lumenal surface of these epithelial cells is composed of plaques separated by interplaque regions. Within the plaques are hex...

This high resolution micrograph of Paramecium multimicronucleatum is adapted with permission from Fig. 1 in J. Cell Biol. 49:1-20, 1971. Paramecium is covered with cilia which arise from regular surfa...

boi controls follicle stem cell proliferation. Germaria from boi[e] mutant in which germ cells (blue, anti-Vasa) and differentiating follicle cells (red, anti-Fas3) are labeled. Stalks between the ger...

This is one of six images in Figure 6 in Apaja et al., JCB 2010 that shows the fate of various model membrane proteins, that are either folded or in the unfolded state at the plasma membrane, expresse...

Electron micrograph of PC12 cells transfected with control siRNA. PC12 cells were plated onto aclar film discs (Pella) coated with poly-L-lysine, transfected twice with 50 nM control siRNA and fixed w...

Electron micrograph of PC12 cells transfected with AP-3 siRNA. PC12 cells were plated onto aclar film discs (Pella) coated with poly-L-lysine, transfected twice with 50 nM AP-3delta1 siRNA and fixed w...

A transverse section near the mid region of the oral proboscis of Didinium. This micrograph shows the extrusive organelles of the mucocysts adjacent to the plasma membrane and the toxicysts. The pexic...

A glancing view of the cortex of Conchophthirus reveals details of cortical structure. This includes the nature of the cell membrane and the alveolar membranes that reside immediately below the surfac...

One parasomal sac lies anterior to each basal body of the somatic ciliature. A parasomal sac is an indentation of the plasma membrane that penetrates into the cytosol past the alveolus. Most sacs end ...
