The decorated spongiome of the CVC is composed of 50nm tubules that have a pattern of helically wound subunits attached to their cytosolic surfaces. These tubules can be up to one micrometer or more i...

Accumulations of acidosome-like vesicles are sometimes found (in this case in a predividing cell) and in this micrograph provide further evidence for invaginations of the outer membranes. It appears t...

A 3D reconstruction of the cardiac outflow tract (OFT) region (horizontal and vertical rotation) from stage-14 wild-type embryo stained for Tinman (Tin; red) and Msp300 (green). Tin staining reveals t...

Immuno-gold labeling of corn stunt spiroplasma (CSS, Spiroplasma kunkelii, Class Mollicutes) in sieve elements and other phloem cells of infected maize root tissue. In this image, CSS appears to be cr...

Transmission electron micrograph illustrating the 'classic' appearance of the nucleus in osmium tetroxide fixed material. In this pancreatic acinar cell nucleus, the only prominent feature is the lar...

Transmission electron micrograph of a bone marrow orthochromatic erythroblast from guinea pig showing terminal differentiation in erythrocyte formation. Accompanying the cessation of most transcriptio...

HeLa cells were processed for indirect immunofluorescence with antibodies to two nuclear pore components, ELYS (embryonic large protein derived from yolk sac) and mAb414 against the FG nucleoporins. B...

Transmission electron micrographs showing annulate lamellae from a frog oocyte. Annulate lamellae consist of stacked sheets of membrane containing closely packed structures resembling nuclear pores a...

Transmission electron micrograph of stacked annulate lamellae from the oocyte of the sea urchin Arbacia. Annulate lamellae consist of sheets of membrane containing closely packed structures resemblin...
