Cytoskeleton. Coloured scanning electron micrograph (SEM) of the cytoskeleton of a human skin cell. The cell nucleus is oval. The rest of the cells' contents have been biochemically extracted. The cytoskeleton is made up of three types of proteins; actin filaments, microtubules and intermediate filaments. The cytoskeleton maintains the cell's shape, allows some cellular mobility and is involved in intracellular transport. Magnification x3000 when printed at 10 centimetres wide.
