Growth-promoting action and growth factor release by different platelet derivatives

Abstract: Platelet derivatives are commonly used in wound healing and tissue regeneration. Different procedures of platelet preparation may differentially affect growth factor release and cell growth. Preparation of platelet-rich fibrin (PRF) is accompanied by release of growth factors, including platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF) and transforming growth factor β1 (TGFβ1), and several cytokines. When compared with the standard procedure for platelet-rich plasma (PRP), PRF re… Show more

“…TGFB1, a ligand of the TGFB signaling pathway, is present in numerous cell types. TGFB1 is most highly concentrated in healing wounds, where it is released in large quantities from platelets (17). TGFB1 then recruits monocytes and macrophages to the injury site (18), inhibits epithelial cell proliferation and enhances fibroblast maturation into post-mitotic fibrocytes that increase fibrous tissue production (19,20), thereby accelerating angiogenesis and extracellular matrix formation (21)(22)(23).…”

“…Kako nije postojala fibrinska mrežica (za razliku od PRF-a), otpuštanje faktora rasta bilo je nekontrolirano i kratkotrajno. Upravo postepenom razgradnjom fibrinske mrežice na mjestu primjene PRF-a postiže se produljeni učinak otpuštanja faktora rasta, što je, uz jednostavniju pripremu, i glavna prednost PRF-a nad PRP-om 3,4 . Produkti trombocita (faktori rasta) koriste se u terapiji kliničkih slučajeva koji zahtijevaju cijeljenje rane i regeneraciju tkiva, a neka područja njihove primjene uključuju: parodontnu, oralnu, maksilofacijalnu i plastičnu kirurgiju, otorinolaringologiju, ortopediju i dermatologiju 3 .…”

“…Nakon aktivacije trombocita zrnca koja se nalaze unutar trombocita poči-nju otpuštati faktore rasta i citokine koji sudjeluju u hemostazi i regeneraciji tkiva. Upotrebom PRP-a ili PRF-a moguće je višestruko povećati koncentraciju aktivnih oblika faktora rasta, koji udruženi s faktorima otpuštenim od susjednih stanica pridonose bržem cijeljenju potičući proliferaciju fibroblasta i zarastanje kosti 2,3 . PRF protokol uključuje prikupljanje pacijentove venske krvi u epruvete koje, za razliku od pripreme PRP-a nisu obložene antikoagulansom.…”
