Naming and classifying platelet derivatives
ОглавлениеNearly 25 years after the earliest reports appeared, the literature on PRP for both human and veterinary medicine still lacks consensus on standardized protocols for preparing, naming, classifying, and applying platelet concentrates. PRP appears to remain the most likely term, given that plasma resuspension of any platelet concentrate is required before application.1 A high-density fibrin concentrate can facilitate cell migration and the release of cytokines. However, the number of leukocytes affects the concentrate’s wound healing ability, leading to the often contradictory results of different studies.
