Autologous Platelet-rich Plasma
What is plasma? Fluid component of a persons blood
Contains platelets, white blood cells, stem cells, electrolytes,enzymes, hormones, nutrients, anti-bodies, glucose, proteins, lipids
& albumin (powerful anti-oxidant), etc. Why autologous? Autologous means persons own (self donated) and not donated
from another person or from animal origin
Growth factors must be in genetically pre-determined ratios!
No risk of rejection and lower allergenic potential
How can A-PRP be obtained easily? Venous blood sample is obtained from patients fore-arm
Centrifugation separates plasma & platelets & stem cells from redblood cells

What is Autologous Platelet-rich Plasma (a-PRP)?
A-Platelet rich plasma is a concentration of humanplatelets in a small volume of plasma measured as1,000,000 platelets per mm3 or 2-6 times the nativeconcentration of whole blood at a pH of 6.5 - 6.7(whole blood pH = 7.0 - 7.2)
Also referred to as autologous platelet gel, plasma-rich growth factors (PRGFs) or autologous plateletconcentrate
PRP is also a concentration of the 7 fundamental
protein growth factorsthat have been proved to beactively secreted by platelets to initiate all woundhealing
PRP includes 3 proteins in blood known to act as celladhesion molecules: fibrin, fibronectin & vitronectin

Advantages of A-PRP
Tissue regeneration & rejuvenation: neo-collagenesis (TGF& ), neo-vascularisation (EGF & VEGF), & extracellular matrix formation (PDGF&& )NB: growth factors in genetically pre-determined ratio!
Bio-glue (fibrin glue): haemostasis & tissue adhesion in skin flaps, bonegrafts, trauma intra-surgery and post-surgery
Safety: non-allergenic & free from concerns over transmissible diseases
e.g. HIV, Hepatitis B & C, CJD, etc. Autologous: no risk of rejection reaction
Wound healing time: increased
Physiological anti-biotic : anti-bodies & WBCs & proteolytic enzymes
Plasma includes: hormones, bio-transformed vitamins & other nutrients
Tissue engineering: in-vitro autologous tissue culture-medium. Ease of use: dermal & hypodermal injections
Convenience: harvesting performed in doctors rooms (no externallaboratory required)
Cost effectiveness: 1 Plasma kit (2 tubes) delivers 12+ ml A-PRP
