Abstract
Platelet enriched plasma is produced from blood. The platelets are activated by thrombin which causes the release of platelet-derived growth and angiogenesis factors. A carrier such as a microcrystalline collagen is added to produce a wound-treating salve. The composition is applied directly to wounds and initiates healing in nonhealing wounds as well as accelerating normal wound-healing by increasing vascularization, stimulating fibroblast mitosis and migration, and increasing collagen synthesis by fibroblasts. The composition is also applied to tissue to facilitate the growth of hair.
