A Novel Platelet Concentrate: Titanium-Prepared Platelet-Rich Fibrin
Figure 4
Scanning electron micrograph. (a) The border between the T-PRF fibrin matrix and cellular components. The RBCs (r) trapped within the fibrin matrix. The leukocytes (l) appeared as spherical structures with an irregular surface. The platelets were often enmeshed in the fibrin network but sometimes appeared as aggregates (p (white circle)) (SEM; original magnification 3500). (b) The T-PRF fibrin matrix. The organized and mature fibrin structure tended to form a network. The RBCs (r) trapped within the fibrin matrix (SEM; original magnification 5000). (c) The border between the L-PRF fibrin matrix and cellular components. The RBCs (r) were trapped within the fibrin matrix. The leukocytes (l) appeared as spherical structures with an irregular surface. The platelets were often enmeshed in the fibrin network but sometimes appeared as aggregates (p (white circle)) (SEM; original magnification 3500). (d) The L-PRF fibrin matrix. The organized and mature line-like fibrin structure with thick and thin fibrils. The RBCs (r) were trapped within the fibrin matrix (SEM; original magnification 5000).
