A murine model is a type of animal model used in biomedical research, specifically involving mice. Mice are widely used in research due to their genetic similarity to humans, their relatively small size, rapid reproduction rate, and the ability to manipulate their genetics. Murine models are used in a variety of research areas, including genetics, immunology, oncology, neuroscience, and drug development. They are particularly valuable in studying human diseases, as many aspects of biology and physiology are conserved between mice and humans. Murine models are also used to study the effects of different treatments and interventions in a controlled laboratory setting before moving on to human clinical trials.
