What is PRP?

Dr. Bill Johnson Discusses Benefits of Fat Transfer for Breast Augmentation

Fat Transfer is a relatively new procedure that can offer patients an alternative to tradition breast implants. The procedure works by removing fat from a patient’s own body, processing it to remove impurities and concentrate fat cells, and re-injecting it into areas of the body where additional fat is desired.

PRP is a special plasma obtained from your own blood. Here is how we get it:

  • First we draw 60 CC’s of the patient’s blood. This is done during the pre-op blood test.
  • Next, a special system called the Harvest system uses a special centrifuge chamber to separate the blood into components.
  • The components are then separated and remixed to obtain the portion of the blood known as PRP.

The PRP contains a high concentration of healing messengers called growth factors. Growth factors are the chemical messengers the body uses to call in healing cells and proteins. The fat that has PRP added is called “SmartFat”. SmartFat can be thought of as sending “text messages” to the body to help promote fat cell survival. PRP also helps the stem cells within the SmartFat to excrete a hormone that helps attract blood to an area. In any fat transfer procedure, if more blood source comes in contact with transferred fat, the better. Finally, PRP SmartFat turns on the stem cells within the transferred fat. These stem cells then become new fat cells. This is important since the human body does not usually replace fat cells that have been killed or suctioned out via liposuction.

What are the Growth Factors in PRP?

You may have heard of PRP already. The use of PRP and growth factors is rapidly spreading in modern medicine. Usually in sports medicine or orthopedics, many people are living better due to this new technology. Even Tiger Woods has used PRP Growth Factors to facilitate healing. Some patients may be interested in the particular growth factors present in PRP. The most predominant growth factors are:

  • Platelet-derived growth factor (PDGF)
    • Stimulates new cells
    • Promotes new blood vessels
    • Promotes healing
  • Transforming growth factor (TGF) – Forms backbone for healing
  • Vascular endothelial growth factor (VEGF) – Promotes new blood vessels
  • Epidermal growth factor (EGF)
    • Promotes cell maturation
    • Promotes new blood vessels
  • Fibroblast growth factor (FGF)
    • Promotes proliferation of endothelial (blood vessel) cells
    • Promotes fibroblasts – the healing/collagen cell
    • Promotes new blood vessels
