Elongated peroxisomes in duodenal epithelial cells. Varying between persons, rounded or elongated peroxisomes are observed. They also vary between epithelial cells on the villus and in the crypt. See:...

Peroxisomes in duodenal epithelial cells proliferate under treatment of oral phytol (a component of chlorophyll) over the course of 3 days. Phytol is oxidized to phytanic acid and pristanic acid, whi...

Representative time-lapse movie of a normal mouse mammary organoid in a 3D collagen I matrix. The cells are expressing td tomato as a membrane marker and eEGFP-actin using a keratin-14 promoter. Ima...

An electron micrograph showing that a centriole is constructed from a ring of nine triplet microtubules. Most animal cells contain two to four centrioles. In longitudinal view, a centriole looks like ...

Liver of a rat exposed to chemical carcinogens. Serial sections of the liver imaged by laser scanning confocal microscopy. F-actin (red) is in bile canaliculi at junctions of the hepatocytes, which ...

Single frog sacculus hair bundle imaged with field-emission scanning electron microscope.

Human duodenal epithelium. Peroxisomes are stained with DAB at pH 10.5 by their catalase activity and postosmicated. 0.5 µm plastic section were visualized using electron microscopy at low magnificat...

Scanning electron micrograph of a hamster oocyte cumulus complex. Cumulus cells (purple) and matrix (gray) are shown. Small blood clots (red) also often appear in oocyte cumulus complexes. The red blo...
