Effect of removal of nonadherent cells, with or without replacement of platelets, on the expression of tissue factor by PBMC in response to homocysteine or LPS.

Results shown are the geometric mean ± SEM of the thromboplastin activity of PBMC from 3 donors, normalized to the monocyte count of the cell preparation at the time of addition to the wells. PBMCs, adherent cells, and adherent cells supplemented with autologous platelets were prepared as described in Materials and Methods.
