Stereo pair of an embedment-free section of a detergent-extracted unfertilized hamster egg. The central region of the egg contains two different types of fibrous networks: a thicker network of sheets that form small whorls and arcs and a thinner network. The sheets are specialized intermediate filament network in mammalian eggs and embryos (i.e., the cytoskeletal whorls) that are parallel bundles of intermediate filaments that disassemble into individual intermediate filaments. Scale bar is 1.0 µm.

Technical Details

Sections were imaged with a Phillips CM300 transmission electron microscope. See Capco DG, McGaughey RW. Dev Biol. 1986 Jun;115(2):446-58 for details on specimen processing. Figure 5 of this paper is a micrograph of a similarly prepared specimen.
