Figure 2.
Representative images of human platelets seeded onto PLLA (A, D), PEG-PLLA (B, E) and hirudin-PEG-PLLA (C, F) surfaces. CD41 mouse anti-human antibody and Alexa Fluor 488 secondary were used to stain platelets on PLLA (A), PEG-PLLA (B) and hirudin-PEG-PLLA (C) surfaces. SEM revealed the morphology and adhesion of platelet on PLLA (D), PEG-PLLA (E) and hirudin-PEG-PLLA (F) surfaces. Scale Bar = 50 µm in A–C, scale Bar = 5 µm D–F. (G) The number of platelets bound to each surface. *P<0.05, n=4. Bar graph shows mean±standard deviation.
