Tensile strength growth factor content and proliferation activities for two platelet concentrates of platelet-rich fibrin and concentrated growth factor

摘要

Platelet-rich fibrin (PRF) can be obtained by centrifuging fresh blood in the absence of anticoagulants. Varying the centrifugation speeds may produce tougher and richer concentrated growth factors (CGF). This study examines tensile strength, growth factor content, and the potential of CGF and PRF in promoting periodontal cell proliferation.
