Which animals can be animal models now?

　　It is the time when people pay attention to animal experiments. The first reaction is the white mouse. In fact, in the professional animal modeling experiments, mice are indeed often used, but the mice we use are called "nude mice".

　　In fact, many animals are ideal experimental subjects. The reason why many choose to use nude mice is because there is no hair on the whole body, and the skin is wrinkled, which looks like a shrunken "old man". It was first discovered by accident in non-inbred mice. In order to find the cause, scientists have made unremitting efforts. It is confirmed that it is caused by genetic mutation and is accompanied by congenital thymus dysplasia, which is called nude mouse. What caused this abnormal state was a recessive mutant gene, called a "naked gene", and the mechanism was thoroughly understood, and a set of standardized animal modeling and maintenance methods was built.
