This is a critical exploration of the potential utility (or otherwise) of Platelet Rich Plasma (PRP) in cosmetic treatments. Please read Part 1 & 2.
|Transforming growth factor beta (TGF-β) is a secreted protein that controls proliferation, cellular differentiation, and other functions in most cells. http://en.wikipedia.org/wiki/TGFbeta (Photo credit: Wikipedia)|
Fibroblast growth factor (FGF) is a "promiscuous" growth factor with multiple actions on multiple cell types. In mature tissues/systems it is mostly involved in angiogenesis, keratinocyte organization, and wound healing processes. Its two variants FGF1 and FGF2 are more potent angiogenic factors than vascular endothelial growth factor (VEGF) or platelet-derived growth factor(PDGF) and can give rise to granulation tissue. FGF can bind heparan sulfates in extracellular matrix and could have a paracrine effect that is very important in PRP.
