What is a genetically engineered mouse?

Genetically engineered mice are laboratory mice whose genetic material has been altered using biotechnology techniques. These modifications can involve adding, deleting, or changing specific genes to study gene function, model human diseases, or test potential therapies. Genetically engineered mice are crucial tools in biomedical research because they can mimic human genetic disorders and help scientists understand disease mechanisms. They are widely used in fields such as genetics, cancer research, immunology, and drug development.
