Rat models are a commonly used research tool in the field of biomedical research. Rats are widely used as model organisms due to their genetic similarity to humans, their relatively short reproductive cycle, and their ease of handling and maintenance in a laboratory setting. Rat models are used to study a wide range of biological processes and diseases, including cancer, cardiovascular diseases, neurological disorders, and drug efficacy and toxicity studies. Researchers use rat models to investigate the underlying mechanisms of diseases, test potential treatments or interventions, and better understand human physiology and pathophysiology. Overall, rat models play a crucial role in advancing scientific knowledge and improving human health by serving as valuable tools for studying complex biological processes and diseases.
