PRP (Platelet rich plasma) is very rich in growth hormone factors and has been used for a lot of orthopedic surgeries and at the dental office after bone graft. It's latest use is in cosmetic skin rejuvination , believe it or not but there are some dermatologist in New York using it instead of botox and it looks very promising. A company called Harvest which is based in Plymouth Ma, makes special centrifuges and collection tubes and is FDA approved for harvesting the PRP for orthopedic and dental surgery. Harvest is being sold to Terumo therefore we might see the practice shifting to the blood bank to prepare the PRP.
