The public, commerical, and medical community are becoming increasingly aware of the potential promise of platelet rich plasma, growth factors, and stem cell therapy. While I use PRP for tendon and cartilage disorders, physicians in South Africa have been using PRP for facial rejuvination and wrinkles by potentially stimulating collagen synthesis.
Also research is being conducted to treat alopecia (hair loss) by stimulating follicular growth. Adult Stem cells the precusor for these proteins may hold the most promise.
It is my opinion that there is much more to be learned regarding PRP. However ultimately we may find that isolating individual growth factors with specific responsibilities may be more effective. Researchers are already working on isolating individual growth factors for specific tasks like cartilage regeneration etc.
