A murine macrophage phagocytosing a Leishmania parasite. Macrophages derived from the bone marrow of a C57/BL6 mouse were co-incubated in vitro with Leishmania mexicana (WHO strain MNYC/BZ/62/M379) st...

Scanning EM of a 24 hr (prim-5) Zebrafish embryo, fractured to reveal the neural tube, notochord and anterior faces of the myotomes. Specimens were chemically fixed critically point dried, and spu...

Scanning EM of the head folds. Specimens were chemically fixed critically point dried, and sputter coated with gold/palladium. This image is part of a series taken by Bryan Crawford while he was at ...

Red blood cells (erythrocytes). This image of human red blood cells obtained by scanning electron microscopy, revealing their characteristic biconcave shape.

Association of plectin with myosin II. A gelsolin-treated REF-52 cytoskeleton immunogold labeled myosin II (10 nm). After actin depletion, intermediate filaments with plectin sidearms remain associate...

Relative distribution of microtubuless and plectin. Electron rnicrograph shows gold-labeled plectin (10 nm) connecting an intermediate filament to microtubules when they cross each other at different ...

Whole human female metaphase chromosome from metaphase arrested cell swollen in hypotonic medium and imaged at 1 MeV. This image was taken with a specimen tilt of 55 degrees. Grouped with it is an im...
