Fig. 5From: Plasma rich in growth factors (PRGF) and leukocyte-platelet rich fibrin (L-PRF): comparative release of growth factors and biological effect on osteoblastsThe presence of leukocytes could explain a faster degradation of the fibrin matrix in L-PRF and thus a faster release of growth factors. In addition, the degree of cross-linking of the fibrin mesh could also affect the release kineticsBack to article page
