Platelet-Rich Plasma (PRP) Therapy
What is PRP?
When asked about the composition of blood the most common answer is RBC, WBC and platelets. What most of us miss is that blood is a liquid (called Plasma) in which these components are contained.
The end-product of the process by which a high concentration of platelets is achieved in small volume of plasma is called Platelet-rich Plasma (PRP).
As we all know platelets play an important role in hemostasis, wound healing and tissue regeneration. In addition, platelets also contain hundred of proteins called growth factors which are very important in healing injuries.
Method– Blood is drawn from the patient and transferred into a test tube having an anticoagulated
– The tube is then centrifuged in a centrifuge machine to separate the RBC, WBC and plasma
– The plasma is collected in a syringe and injected at the location of choice (decided by the Dermatologist and patient)
Mechanism Of Action
Following injury platelets are activated and aggregate together to release a number of growth factors which act on different stages of wound healing. Further, it also contains adhesion molecules which are capable of enhancing cell adhesion and act like matrix for formation of connective tissue.
