Cultured Cells

Most living things are made up of one or more cells. Cells can be as large as an ostrich egg (about 8 centimeters wide) to as small as a mycobacterium (about 0.1 micrometer). Some organisms are composed of only one cell, and others are made up of millions of different kinds of cells.

These are cells that have been grown in a dish, and so they can stick down and spread out if they want to. Some kinds of cells cannot be cultured; others have very special requirements to be cultured. Some cells grow easily and can even form tissues in a dish. Culturing cells makes it easy for us to study them, and to do things like test medicines for diseases and treatments for cancer.
