Fig. 1From: Mechanical and degradation properties of advanced platelet-rich fibrin (A-PRF), concentrated growth factors (CGF), and platelet-poor plasma-derived fibrin (PPTF)Surface microstructures of A-PRF, CGF, and fibrin clots prepared by PPP + CaCl2 and PPTF (fibrin clots prepared by PPP and thrombin). Similar observations were obtained from other three independent blood samples. Scale bar = 10 μm. Note: the same magnification (×9000) was used in all the SEM images shown hereBack to article page
