Fluorescence microscopy of FITC-FN assembly in response to different agonists on FN- or VN-coated coverslips.
After a 15-minute adherence phase, coverslips were incubated for 1 hour with 20 mg/L FITC-FN in the presence of no agonist (0); 0.5, 10, or 20 μM LPA; 10 μM ADP; 20 μM S1P; or 1 U/mL thrombin. Phase contrast microscopy (not shown) revealed monolayers of platelets under all conditions. Bar = 10 μm.
