PRP is a concentration of your own platelets. These platelets normally circulate through the blood and are critical for blood clotting and healing. Platelets and the liquid plasma portion of the blood contain many healing factors. These factors are essential for the cell recruitment, multiplication and specialization that are required for healing. After your blood sample is obtained, it is put into a centrifuge to separate the blood into its many components. PRP can then be collected and delivered to the injured area. Once platelets are in the injured area, they break down and release growth factors, which are compounds that help cells repair and regenerate.
