Confocal micrograph showing the hormone-producing enteroendocrine cells of the Drosophila melanogaster adult midgut. The enteroendocrine cell nuclei are labelled with an anti-Prospero antibody (red), ...

Human duodenal epithelium, at the level of the crypt. Fixation was performed in buffered formal-calcium. Peroxisomes are stained with DAB by their catalase activity at pH 10.5, postosmicated and embed...

Hamster oocyte and cumulus cells. This scanning electron micrograph shows a hamster oocyte. The oocyte is not directly visible but lies beneath the zona pellucida. The surface of the zona pellucida c...

Scanning electron micrograph of single guinea pic pancreatic acinar cells attached to a duct. Image made available by James D. Jamieson and the Department of Cell Biology, Yale University School of ...

Colorized scanning electron micrograph of a human egg. The egg is surrounded by a glycoprotein coat called the zona pellucida which aids in trapping and binding the sperm. Two residual coronal cells f...

Transmission electron micrograph illustrating the 'classic' appearance of the nucleus in osmium tetroxide fixed material. In this pancreatic acinar cell nucleus, the only prominent feature is the lar...
