In search of a consensus terminology in the field of platelet concentrates for surgical use: platelet-rich plasma (PRP), platelet-rich fibrin (PRF), fibrin gel polymerization and leukocytes.

In the field of platelet concentrates for surgical use, most products are termed Platelet-Rich Plasma (PRP). Unfortunately, this term is very general and incomplete, leading to many confusions in the scientific database. In this article, a panel of experts discusses this issue and proposes an accurate and simple terminology system for platelet concentrates for surgical use.

Platelet concentrates for topical use: bedside device and blood transfusion technology. Quality and versatility.

More or less after a decade of experimental and pioneering manual procedures to prepare platelet-rich plasma (PRP) for topical use, several portable and bedside devices were made available to prepare the PRP at the point-of-care. This technical opportunity increased the number of patients who got access to the treatment with autologous PRP and PRP-gel. Since topical treatment of tissue with PRP and PRP-gel was restricted to autologous preparation, blood transfusion centers that professionally prepare donor-derived platelet concentrates were not able to cover the overwhelming request for autologous PRP supply.

Treatment of recalcitrant ulcers with allogeneic platelet gel from pooled platelets in aged hypomobile patients.

We evaluated growth factor contents and clinical efficacy of allogeneic platelet gel (PG) prepared with standard blood banking procedures from routine platelet concentrates (PCs) obtained from buffy coats. The PGs were used to treat 11 hypomobile very elderly patients unable to undergo autologous blood processing and previously ineffectively treated with expensive advanced medications for 8-275 weeks. PGs were prepared by platelet activation with human thrombin or commercial batroxobin.

Platelet-derived factors involved in tissue repair-from signal to function.

Topical treatment with platelet derivatives has increasingly been described as being capable of accelerating wound healing and to aid in tissue repair. In vitro data indicate that platelets and their contents have chemotactic, migration-inducing, and mitogenic activities, and a major role of these factors in tissue repair has thus been advocated. However, how platelet-derived factors orchestrate tissue repair at the cellular level remains quite obscure even to those individuals who prescribe platelet derivatives as topical wound healing therapy.

Not every PRP-gel is born equal. Evaluation of growth factor availability for tissues through four PRP-gel preparations: Fibrinet, RegenPRP-Kit, Plateltex and one manual procedure.

Background: The rationale for using topical platelet gel therapy is to provide the healing tissues with concentrated platelet-derived factors. Several systems are available to prepare platelet-rich plasma (PRP) and from these, the platelet gel. These systems produce two- to six-fold platelet and growth factor-enriched concentrations.
