Confocal micrograph of a mast cell in human eye with conjunctivitis. This image shows a single mast cell invading conjunctival tissue in response to an inflammatory agent or pathogen. The mast cell c...

Multiphoton image of microglia (GFP, green) and cerebral blood vessels (Texas-red dextran, red) in living, anesthetized transgenic mouse. Microglia are glial cells that are the resident macrophages. H...

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...

Figure 175 from Chapter 5 (Endoplasmic Reticulum) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Electron micrograph of a plasma cell from guinea pig bone marrow. Active synthesis of immunoglobulin b...

Scanning electron micrograph of two human bone-forming cells (osteoblasts) crawling over crystals of the ceramic material,. monetite (CaHPO4). Monetite crystals are electrochemically deposited onto ti...

This scanning electron micrograph shows mycroplasma (colorized pink), a genus of bacteria that lack a cell wall. Without a cell wall they are unaffected by many common antibiotics, such as penicillin,...

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 ...
