Figure 6. RBCs and fibrin networks from healthy individuals with SF levels within normal ranges.

A) RBC B) RBC with added thrombin; C) Platelet rich plasma smear with added thrombin. D) Typical light microscopy smear from a healthy individual. The cell arrowed illustrates the means by which we determined the axial ratios. E) Healthy RBC exposed to physiological levels of iron. F) Healthy PRP exposed to physiological levels of iron showing matted masses (white arrows). All SEM micrographs scales = 1 µm; Light microscopy scale = 10 µm.
