Platelets are small, colorless, cell fragments present in the blood. They are formed in the bone marrow and are freely passing through the bloodstream in a resting state. However, when an injury occurs, the platelets become activated and start to gather at the injury site to release beneficial proteins called Growth Factors. This is the beginning of the healing process.
Platelet Rich Plasma is a concentration of platelets and growth factors created from a small amount of your own blood or bone marrow. A sample of your blood or bone marrow is put through a rapid spinning process that separates and concentrates the platelets and other beneficial growth factors from the blood. Increased levels of growth factors have the potential to improve signaling and recruitment of cells. This concentrated portion of the blood or bone marrow is often referred to as platelet-rich plasma (PRP). For more information on PRP, visit AOA’s Stem Cell website.
