[0002] Laboratory mice refer to mice that have been artificially raised and selectively bred, and are mainly used for scientific research and experiments. They belong to the phylum Vertebrata, class Mammalia, order Rodentia, and family Muridae. Laboratory mice are usually bred from house mice through multiple generations of selection. They have stable genetic characteristics and are often used in research in genetics, epidemiology, and oncology. Laboratory mice play an important role in scientific research and experiments. They are widely used in the production of medicines, vaccines, and biopharmaceuticals, surgical practice, quality inspection and safety evaluation of new drugs, foods, and drugs, as well as research in life sciences. Laboratory mice have strong reproductive capacity, can produce multiple pups at a time, and are easy to raise and manage, making them indispensable experimental animals in laboratories.
