Platelet, cTF, and fibrin movement.

Platelet (green) and fibrin (blue) movement across collagen-coated glass slides at 650 s⁻¹ wall shear rate. Time sequence of images: (A) 30 seconds; (B) 2 minutes; (C) 10 minutes; (D) 15 minutes; (E) 20 minutes. Adhesion of platelets (green) as well as fibrin (blue) strands occurred within about 15 minutes of blood flow. The first cTF (red) signal was obtained after 20 minutes of flow. The direction of blood flow is from top to bottom. Original magnification × 20.
