Transmission electron micrograph of a dividing myelocyte from the slender salamander Batrachoseps attenuatus showing mitotic chromosomes at late prophase.

Figure 238 from Chapter 7 (Mitochondria) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Mitochondria from brown adipose cells can attain a diameter of 5 to 7 µm (for scale, compare with the portion o...

Transmission electron micrograph of continuous endothelium from a rat diaphram capillary. Image aIso shows a reticulocyte in the capillary lumen. Image made available by James D. Jamieson and the De...

Early transmission electron micrograph showing an alpha cell in the Islet of Langerhans in the guinea pig pancreas. Alpha granules are prominent among the mitochondria, and a portion of nucleus is al...

Scanning electron micrograph of a 6 day old human embryo beginning to implant into the lining of the uterus (endometrium). As implantation progresses, the inner cell mass begins to form into the bila...

Imaging an HIV infected dendritic cell reveals numerous viral particles at the tips of filopodia. Actin-based membrane extensions from the dendritic cell are phallodin stained (red). HIV particles (wh...

Peroxisomes in cultured rat hepatocytes have proliferated under treatment with 4-phenylbutyrate. The animal was transgenic for PPARalpha -/-, so phenyl butyrate acts without the PPAR receptor.

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