Preclinical research refers to scientific studies conducted in the laboratory using cells, tissues, and animal models to investigate the biological mechanisms underlying diseases, test potential new drugs or therapies, and evaluate their safety and efficacy before moving to clinical trials in humans. This type of research is essential for identifying promising treatments and understanding how they may work in treating various diseases. Preclinical research helps researchers gather important data and evidence to support the development of new medical interventions and advancements in healthcare.
