  • *Cellular subsets are deduced according to their phenotype.

  • Monoclonal antibodies directed against those surface molecules were used to purify corresponding cell type as described in Materials and Methods.

  • Range of cells used in the PCR assays.

  • F1-153 Negative fraction collected at the end of the magnetic selection and corresponding to the CD15, CD14, CD19, and CD3 cells. This fraction was depleted in nucleated cells and contained principally thrombocytes.
