Platelet Rich Plasma is an autologous high concentration of platelets in a small volume of plasma. It is measured as 1 million platelets per mL, or at least 2 times the native concentration of whole blood. About 50% of blood is made up of plasma; it is relatively clear with yellow tint made up of water (92%), sugar, fat, protein and salt.
Utilized in a variety of surgical and non surgical applications:
- dentistry
- wound healing
- pain management
- dermatology
- plastic surgery
- hair restoration
- aesthetics
Platelets release growth factors which initiate the healing cascade:
- PDGF (Platelet Derived Growth Factor) promotes synthesis of extracellular matrix
- TGF (Transforming Growth Factor) synthesis of collagen
- EGF (Epidermal Growth Factor) proliferation and differentiation of epidermal cells
- VEGF (Vascular Endothelial Growth Factor) stimulates angiogenesis
The initial response to tissue injury:
- Clotting/Hemostasis Fibrogen creates fibrin strands Activated Platelet membrane
- Inflammation (remove debris) Platelet signaling proteins WBC signaling proteins
- Tissue regeneration (new cell growth) Platelet Growth Factor (PDGF, TGF, EGF) WBC signaling proteins (VEGF) Plasma Growth Factors (IGF) Adhesion molecules (Fibronectin, SC Factor, Victronectin, Vascular Cell Adhesion Factor)
