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.

Shown is a a confocal microscope image of a human gingival fibroblast in culture. Interphase microtubules (green) are labeled with alpha/beta tubulin primary antibodies. FITC conjugated secondary anti...

This transmission electron micrograph of a section through a late orthochromatic erythroblast (normoblast) from human bone marrow shows shallow depressions along the membrane surface, indicated by arr...

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...
