This scanning electron micrograph shows the internal structure of liver tissue from an adult mouse. The sinusoids (vascular channels lined with endothelial cells) can be seen as pink structures runnin...

Shown is a hematoxylin and eosin stained section through a plasmablastic lymphoma of the oral cavity in an HIV-positive adult male. There is a diffuse proliferation of large neoplastic cells most of w...

Figure 391 from Chapter 15 (Cytoplasmic Inclusions) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Secretory granules of a mast cell from rat connective tissue. Secretory granules in this cell type ar...

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...

Pseudopods jut out from this polymorphonuclear leucocyte of the guinea pig to enable amoeboid motility. Organelles are initially excluded as the pseudopod first forms, but they flow in as the pseudopo...

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 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...

Two monocytes with cytoplasmic erythrocytes were detected (upper part and lower right corner of the photo). The two other cells show erythrocytes at contact (one of which also a rectangular crystal). ...

Monocyte-type cells of elongated form, fibroblast-like, showing nucleus compression by 2 erythrocytes. The erythrocytes seem rather at contact to the cell or superposed and not intracytoplasmic. To no...
