Platelet-rich plasma (PRP) is a technique used in regenerative medicine that involves isolating and concentrating platelets from a sample of the patient's own blood. Platelets contain growth factors and other proteins that are involved in tissue regeneration and healing. PRP is often used in sports medicine to treat injuries such as tendonitis, ligament sprains, and muscle strains, as well as in cosmetic procedures to improve skin tone and texture. Research in the area of PRP is focused on understanding its mechanisms of action, optimizing PRP preparation techniques, and exploring its potential applications in various medical fields.
