X-ray scattering shows that the nucleated erythrocytes of the amphibian Necturus maculosus (Mud Puppy) contain more ordered chromatin than most nuclei. Here, fibers isolated from these nuclei have bee...

chicken erythrocyte nuclei were allowed to decondense in a low salt high pH buffer, fixed with HCOH, centrifuged onto a carbon coated EM grid, and stained with uranyl acetate. (Spreading technique of ...

Scanning electron micrograph of the surface of a peritoneal mast cell from mouse shows undulating folds, and few microvilli. The membrane folds could be misinterpreted for microvilli if analyzed in t...

Confocal micrograph of osteoblast cells labeled with Alexafluor 488 that stains alpha tubulin (green) and phalloidin marking the actin (purple) and DAPI highlighting the nucleus (yellow). Osteoblasts...

Transmission electron micrographs showing details of nuclear pores in thin sections of an erythroblast (above) and endothelial cell (below). Pores appear to be filled with dark staining material in th...

Figure 237 from Chapter 7 (Mitochondria) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Mitochondria in cells of brown adipose tissue (shown here in interscapular brown fat of the bat) are dense, and ...

Figures 412 (upper) and 413 (lower) from Chapter 16 (Cytoplasmic matrix and cytoskeleton) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Persisting interzonal spindle microtubules in telophase of divi...

Video showing HIV-1–infected human macrophage sensing its environment. Images were collected on a spinning disk confocal microscope using a 100X objective. Honorable Mention, 2011 Olympus BioScapes...

This colorized scanning electron micrograph shows the structure of osteocyte cells in the cortex of a mouse tibia bone. Osteocytes are the cells that form new bone. Imbedding the bone in resin, which ...

Light micrograph of elastic cartilage of the ear. This type of cartilage is made from a protein called elastin and is formed from a network of elastic fibers and collagen. The fibers form bundles whic...
