Abstract
In vitro and in vivo application of sub-atmospheric, negative pressure on growth factor starting material, such as whole blood, extracts growth factors from the platelet granules of the growth factor starting material in a non-destructive medium without activating the clotting process. The extracted growth factors are released into a growth factor composition containing blood plasma, extracellular fluid or interstitial fluid depending upon the type and location of the growth factor starting material. The growth factors have a weight of about 70-76 kDaltons and are applied in either a filtered or unfiltered state topically to the area of a surface wound to effect healing. The extracted growth factors are also injected into soft tissue, such as a torn tendon, to promote tissue growth and healing. The growth factors are released in one method from a patient's own blood. In another method the growth factors are released from a whole blood source and freeze dried by lyophilization. Then at a later date, the freeze-dried product is reconstituted by normal saline for treatment of a patient's wound, for use in a surgical procedure, or for tissue regeneration.
