Dividing cells from the liquid endosperm of the lily Haemanthus katherinae were fixed with paraformaldehye, embedded in epoxy, and 1.0 micrometer sections prepared. Images were obtained with the Wisco...

Fat bodies from 3rd instar larvae of Drosophila melanogaster were dissected, fixed with formalin and stained with uranyl acetate, embedded in epoxy resin, and 0.5 micrometer sections prepared (see Ris...

Quick-freeze deep-etch image of a cytosolic region where trichocysts are developing. Vesicles, even small ones, contain contents that are compacting into paracrystalline form. These vesicles seem to h...

Color-enhanced scanning electron micrograph of the inside of a guinea pig inner ear showing the hearing organ, or cochlea. Running along the spiral structure are rows of sensory cells which respond to...

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...

Colorized scanning electron micrograph of keratinised squamous epithelial lining of the upper vagina. The boundaries between adjacent cells are visible as raised ridges. The cells closest to the surfa...

This colorized scanning electron micrograph shows the structure of osteocyte cells in the cortex of a mouse tibia bone. Osteocytes are the cells that form new bone. Imbedding the bone in resin, which ...
