Culture cell. Confocal light micrograph of a 3t3 (mouse fibroblast) cell in culture. The nucleus is blue. Protein fibres making up the cell's cytoskeleton are red and green. The cytoskeleton is a network of structural proteins, such as actin and tubulin, that supports the cell's organelles and other internal structures. 3t3 cells are an immortal cell line widely used in biological research. Magnification: x1000 when printed 10cm wide.
