A European Study from Oct 07′ by Anitua & Sanchez et al. injected 10 osteoarthritic patients with PRP & studied the cellular effects of PRP. They found an increase in hyaluronic acid concentration, balancing cell proliferation (angiogenesis). However, there was no effect on IL 1-B, which generally plays a role in osteoarthritis. This information gives us insight into how PRP may potentially benefit arthritis.
Platelet-released growth factors enhance the secretion of hyaluronic acid and induce hepatocyte growth factor production by synovial fibroblasts from arthritic patients

It’s important that we better understand the mechanism that PRP may potentially benefit arthritis. New insights may direct more specific treatments in the exciting realm of Biologics.
