The self-clotted types of platelet concentrates (PRF) can be prepared from ACD-containing stored WB by addition of CaCl2 without a significant reduction in their bioactivity and without other specific reagents or devices. This approach should contribute to dissemination of PRF therapy.

Similar observations were obtained from WB samples collected from three other donors. Scale bars = 10 μm : Platelet-rich fibrin prepared from stored whole-bl
- Fig. 4. Bioactivities and PDGF-BB concentrations in PRF extracts and the supernatant serum fraction. a PRF extracts were added to periosteal cell cultures and incubated for 3 days to evaluate their effects on cell proliferation. No significant differences were observed among three groups. b PRF extracts were subjected to measurement of PDGF-BB levels using an ELISA kit. No significant differences were observed in the supernatant among three groups. N = 6. c Representative localization of supernatant serum fraction of PRF preparation just after centrifugation : Platelet-rich fibrin prepared from stored whole-bl
