Effect of annexin V on thrombin generation by apoptotic VSMC-myc cells. Apoptotic VSMC-myc cells were collected and resuspended as before and then incubated at room temperature for 30 minutes with and without 5 μmol/L annexin V. Thrombin generation curves are shown for apoptotic cells (□) and annexin V-treated apoptotic cells (⋄).
