Cell culture involves removing cells from an animal or plant and growing them in a favorable artificial environment. There are several types of cell culture, including primary cell culture derived directly from tissue, and secondary cell culture involving subculturing primary cells. Common cell culture equipment includes incubators, hoods, media, microscopes, and refrigerated storage. Standard procedures involve harvesting cells, transferring them to growth media in a culture dish, incubating, and subculturing as needed to maintain the cells.
