Platelet-Rich Plasma (PRP)

PRP is an autologous biologic derived from whole blood that is preferentially enriched for platelets.

While platelets are the primary component of PRP, preparations may also contain other cellular components such as white blood cells (WBCs) and peripheral stem cells. These components all play a biological role in the healing process and are provided at concentrated levels in PRP. Thus, PRP may help optimize the conditions for healing of bone and soft tissue.

Platelets White Blood Cells Progenitor Cells


Platelets play a critical role in several aspects of the healing process. Activated platelets express adhesion molecules that support clot formation for hemostasis. They also release several antimicrobial peptides that deliver properties for infection control. Most importantly as it relates to healing, platelets also release chemokines and numerous growth factors, including SDF-1α, PDGF, TGF-β and VEGF, that have been shown to orchestrate key biological processes, including angiogenesis, inflammation resolution and tissue regeneration.1,2,3,4

White Blood Cells

White Blood Cells (WBCs)
WBCs (leukocytes) play a key role in protecting the body from infection and coordinating the inflammatory response. The three primary classes of cells found in the WBC population each provide unique biological functionalities:
  • The “immediate response” cells for prevention of infection
  • Key mediators of inflammatory response through phagocytosis and release of reactive oxygen species (ROS)

  • T-lymphocytes help regulate the function of other immune cells and directly attack various infected cells and tumors
  • B-lymphocytes make antibodies, which are proteins that target unwanted bacteria, viruses and other foreign material

  • Assist in pathogen recognition
  • Eventually become macrophages, which engulf and destroy pathogens
Nonspecific Inflammatory Response
WBCs travel through the body to address inflammatory conditions.

Progenitor Cells

Progenitor Cells
Progenitor cells convert to terminal tissue and support angiogenesis. Endothelial progenitor cells also retain the ability to differentiate into other cell types, but to a lesser extent than stem cells.5,6

Help Optimize the Conditions Needed for Healing With PRP

The concept behind the clinical use of PRP is to harness the natural biological components of a patient’s blood―primarily platelets―which may help optimize the conditions for healing, improve inflammatory response, control infection and promote angiogenesis.7,8,9
Platelets facilitate healing through release of many growth factors actively involved in this process. Thus, PRP offers the physician an alternative to other widespread options, such as steroid injections that provide short-term relief by masking symptoms such as pain and inflammation that are the result of an injury, rather than actually addressing the cause of the injury directly through repair of damaged tissue.10,11,12

High Concentrations of Key Growth Factors

Platelet concentration is directly proportional to growth factor concentration.13

When more platelets are concentrated in a PRP preparation, more growth factors are delivered to the application site. These growth factors support several key processes, including stem cell recruitment, angiogenesis, cell proliferation and differentiation.14
PRP provides high concentrations of several key growth factors involved in healing and tissue regeneration, including:

Risk Information: These procedures require needle access, possibly resulting in discomfort, tenderness, bruising, swelling, bleeding or pain at the access site, at which there is a small risk of infection. Lightheadedness, fainting, nausea or vomiting may occur. Before any medical procedure, review prescription and nonprescription medications and any natural or herbal remedies your patient is taking or plans to take.
